If you are applying for a Student visa from inside the UK, this page answers some of the most common questions about whether you are eligible to apply, academic progression, your CAS, supporting documents, financial requirements, dependants, making your application, and what happens while you are waiting for a decision. Applying from inside the UK is subject to additional requirements, including rules about switching immigration categories, application timing and your current immigration status, so you should read this guidance carefully alongside the official gov.uk Student visa information and advice provided by UKCISA.

You should read the official gov.uk Student visa guidance before submitting your application. This explains the eligibility requirements, documents you may need, application fee and how to apply.
The UK Council for International Student Affairs (UKCISA) also provides detailed independent guidance for international students applying for a Student visa from inside the UK.
Applying from inside the UK is different from applying from outside the UK. In particular, you need to check the specific eligibility conditions.
Immigration requirements can change, so you should always check the latest guidance before submitting your application.
If you are unsure whether you are eligible to apply from inside the UK, contact International Student Services before submitting an application.
You may be able to apply for a Student visa from inside the UK if you currently have valid UK immigration permission that allows you to switch to, or extend under, the Student route.
You must normally:
If you do not meet the requirements for an application from inside the UK, you will normally need to leave the UK and make your Student visa application from overseas.
If you are unsure whether you are eligible to apply from inside the UK, contact International Student Services before submitting an application.
The earliest you can apply for a Student visa from inside the UK is three months before the course start date shown on your CAS.
You must submit your application before your current immigration permission expires.
Your new course must also start no more than 28 days after your current immigration permission expires.
If you are applying for additional permission to continue a course you are already studying, for example because you need more time to complete a PhD, the three-month restriction does not apply in the same way.
You should apply as soon as reasonably possible once you:
UKVI currently advises that Student visa applications made inside the UK are usually decided within eight weeks.
No.
If you are applying for Student permission from inside the UK, for a new course, your new course must start no more than 28 days after your current immigration permission expires. For example, if your current immigration permission expires on 1 January, your new course must start no later than 29 January.
If the gap is more than 28 days, you will normally need to leave the UK and make your Student visa application from overseas.
The 28-day requirement applies regardless of the type of immigration permission you currently hold.
Please note, the 28-day rule is a mandatory eligibility requirement for Student visa applications made from within the UK. It is based on the time between the expiry of your current immigration permission and the start date of your new course, regardless of when your CAS is issued or your visa application is submitted.
As this requirement is set by the Home Office, the University has no discretion to waive or extend the 28-day period. We are also unable to amend the course start date to accommodate individual visa circumstances.
If you currently have, or previously had, Student or Tier 4 (General) permission and want to make another Student visa application from inside the UK, you will normally need to meet the academic progression requirement.
In most cases, this means you must have successfully completed the course for which your previous Student permission was granted and your new course should normally be at a higher academic level.
A new course at the same academic level may be permitted where it is at degree level or above and the University can confirm that:
There are also specific exceptions, including circumstances where you need additional Student permission to complete your existing course, repeat modules or resit examinations.
If your proposed study does not meet the academic progression requirements for an application made inside the UK, you may still be able to study the course, but you would normally need to leave the UK and apply for your Student visa from overseas.
International Student Services will assess academic progression before issuing a CAS for an application from inside the UK.
Many people who already have valid UK immigration permission can switch to the Student route from inside the UK.
However, you cannot normally switch to the Student route if you currently have, or were last granted, permission as:
You must also not be on immigration bail.
If you are in one of the categories from which switching is not permitted, you will normally need to leave the UK and apply for a Student visa from overseas.
If you have settled or pre-settled status under the EU Settlement Scheme, you do not normally need a Student visa.
No.
The University will not issue a CAS while you have an outstanding immigration application with the Home Office, including a pending Further Leave to Remain (FLR) application.
We will also not issue a CAS so that you can vary an existing immigration application to the Student route.
If you have submitted an FLR or other immigration application, to remain in the UK beyond the expiry date of your previous visa, you must wait until the Home Office has made a decision.
Once you have received that decision, we can assess whether:
Alternatively, you may choose to leave the UK and, if eligible, make a Student visa application from overseas. Your eligibility for a CAS would then be assessed in accordance with the University’s admissions and immigration requirements.
Please remember that receiving an unconditional offer of a place on a course does not guarantee that you will receive a CAS.
CAS eligibility is assessed separately. We can only make this assessment once you have completed your CAS Shield application and provided all of the supporting evidence requested.
You should submit your Student visa application before your current immigration permission expires.
If your immigration permission expires before you make a valid new application, you will normally become an overstayer. Overstaying can have serious consequences for your immigration status and future immigration applications.
Although the Immigration Rules contain limited circumstances in which a short period of overstaying may be disregarded, you should not rely on these provisions in order to make a Student visa application.
The University will not normally issue a CAS to support an application from inside the UK where you have overstayed your immigration permission.
If your visa is due to expire and you do not think you will be able to submit a valid Student visa application in time, contact International Student Services immediately. You may need to leave the UK before your current permission expires and apply from overseas.
Your CAS can normally be used to make a Student visa application for up to six months from the date it was assigned.
You must also make your application no more than three months before your course start date.
A CAS can only be used for one visa application. Once it has been used, it cannot normally be used again.
If your previous visa application was refused or withdrawn, contact International Student Services before making another application. We will need to determine whether a new CAS is required.
Check your CAS carefully as soon as you receive it.
In particular, check your:
If any information appears to be incorrect, contact us before submitting your Student visa application.
Do not submit an application using information that you know is incorrect and assume that it can be corrected afterwards.
No. If you make an additional advance tuition fee payment after your CAS has been issued, do not assume that your CAS will automatically show the new payment.
Contact the University using the contact details provided with your CAS so that we can check that your payment has been received and update your CAS where appropriate.
Tuition fees you have already paid can normally be deducted from the amount you need to demonstrate for your visa application, where the payment is recorded on your CAS or otherwise evidenced in a way permitted by UKVI.
You should therefore check the financial information on your CAS before submitting your application.
Some students studying or researching particular subjects at postgraduate level require an ATAS certificate. If ATAS is required for your course, this will be identified in your Unconditional offer letter, as in the example below.
“Please note, it has been identified that you will require an ATAS certificate to study this programme. Please see this webpage for more information. ATAS can take over 4 weeks to complete, so please apply for this as soon as possible.
The Common Aggregate Hierarchy (CAH3) code you will need for your ATAS application is: CAHxx-xx-xx”
To apply for an ATAS certificate, you will need to know the CAH3 code that has been identified in your offer letter.
You must receive your ATAS certificate before submitting your Student visa application.
The course information in your ATAS application should match the information provided by the University.
ATAS applications can take several weeks and there is no priority service, so you should apply as early as possible.
You can check whether ATAS applies to you on gov.uk.
No. Your passport does not normally need to remain valid for the entire length of your course.
However, it must be valid when you make your Student visa application.
If you obtain a new passport after your CAS has been issued, contact us before submitting your visa application so that we can check whether your CAS information needs to be updated.
You should also make sure that your current passport or travel document is correctly linked to your UKVI account.
Exactly what you need will depend on your individual circumstances. You should check the current gov.uk Student visa guidance before submitting your application.
You will normally need:
Depending on your circumstances, you may also need:
If you have been living in the UK with valid immigration permission for at least 12 months on the date of your application, you will normally meet the Student financial requirement automatically and will not ordinarily need to provide evidence of your course fees or living costs. However, UKVI may still request financial evidence, so you may wish to consider preparing the relevant documents in advance, in case they are needed.
Your online application will provide a document checklist.
Documents used for your visa application must be in English.
If an original document is in another language, you must normally provide the original document together with a fully certified translation.
The translation should confirm that it is an accurate translation of the original document and should include:
You should not translate documents yourself.
The University of Gloucestershire is a ‘Higher Education Provider with a track record of compliance’. As such, students applying to study a degree-level course or above will normally not need to submit their academic qualification certificates or English language evidence with their Student visa application.
The University will confirm on your CAS how your academic suitability and English language ability were assessed. You should still keep these documents available, as UKVI can ask you to provide additional evidence during the visa application process.
If you have been living in the UK with valid immigration permission for at least 12 months on the date of your application, you will normally meet the Student financial requirement automatically and will not ordinarily need to provide evidence of your course fees or living costs. However, UKVI may still request financial evidence, so you may wish to consider preparing the relevant documents in advance, in case they are needed.
If you have been in the UK for less than 12 months, you will normally need to meet the financial requirement in the usual way.
If you have been living in the UK with valid immigration permission for at least 12 months on the date of your application, you will normally meet the Student financial requirement automatically and will not need to provide evidence of your course fees or living costs.
If you have been in the UK for less than 12 months and are required to meet the Student visa financial requirement, you should normally provide appropriate financial evidence.
However, nationals of certain countries and territories benefit from the Student visa differential evidence arrangements. If this applies to you, you may not normally need to submit financial evidence with your application. This does not mean that you are exempt from the financial requirement. You must still meet the requirement on the date you apply, and UKVI can ask you to provide the evidence while your application is being considered.
We therefore recommend preparing compliant financial evidence before you apply, even where you are not required to submit it initially.
Please refer to our Student route financial requirements webpage for further information.
If you do not qualify for the 12-month financial exemption, or do not benefit from the Student visa differential evidence arrangements, you will normally need enough money to cover:
1. Your outstanding course fees
You must have enough money to pay any course fees due for the first academic year of your course, or the whole course if it lasts less than one year.
The amount will be shown on your CAS.
Advance tuition fees you have already paid to the University can normally be deducted where they are recorded on your CAS or otherwise evidenced as permitted by UKVI.
2. Your living costs
As the University of Gloucestershire is outside London, for Student visa applications made before 30 November 2026 you must normally show £1,171 for each month of your course, up to a maximum of nine months.
This means the maximum living-cost requirement is currently £10,539.
For Student visa applications made on or after 30 November 2026, this requirement will increase to £1,203 per month for up to nine months.
The maximum will therefore become £10,827.
Always check the current gov.uk financial requirement before submitting your application.
Please refer to our Student route financial requirements webpage for further information.
The Student visa rules allow several ways of meeting the financial requirement.
Depending on your circumstances, you may be able to use:
If you are relying on money in a bank or building society account, the required amount must normally have been held for at least 28 consecutive days.
The final date of that 28-day period must normally be no more than 31 days before the date you submit your visa application.
The money must be immediately accessible to you.
Some types of funds cannot be used, including shares, bonds, credit cards, overdrafts and cryptocurrency.
Please refer to our Student route financial requirements webpage for further information.
If you are required to meet the Student visa financial requirement, yes.
You can normally use money held by your parent or legal guardian to meet the Student visa financial requirement.
The financial evidence must meet the normal Student visa requirements, including the 28-day requirement where applicable.
You must also normally provide:
Please refer to our Student route financial requirements webpage for further information.
If you are required to meet the Student visa financial requirement, a certificate of deposit can be acceptable provided it meets the Home Office requirements, including evidence that the required money has been held for the necessary 28-day period and that you can access the funds.
You should check the exact wording of your document carefully before relying on it.
Please refer to our Student route financial requirements webpage for further information.
This will only be relevant if you are required to meet the Student visa financial requirement, in which case you can reduce the amount you need to show for living costs, but only in certain circumstances.
There is a limited concession if you have already paid money to the University for accommodation in halls of residence.
You cannot normally deduct payments made for private rented accommodation, private halls, a hotel, Airbnb or other accommodation that is not provided by the University.
For applications made before 30 November 2026, the maximum permitted accommodation deduction is currently £1,529. From 30 November 2026, this amount will increase to £1,570.
Please refer to our Student route financial requirements webpage for further information.
If your money is held in a currency other than British pounds (GBP), UKVI will normally convert the funds into GBP using the OANDA exchange rate on the date of your visa application.
Exchange rates can change from day to day.
You should therefore avoid holding exactly the minimum amount required.
We strongly recommend maintaining a reasonable financial buffer so that a change in the exchange rate does not cause your funds to fall below the amount required when you submit your application.
Please refer to our Student route financial requirements webpage for further information.
You should not submit a Student visa application unless you meet all of the relevant financial requirements on the date you apply.
Where you are required to provide financial evidence, the money and documents you rely on must meet the requirements of the Immigration Rules.
Submitting an application without the required funds, or relying on financial evidence that does not meet UKVI requirements, creates a significant risk that your application will be refused.
The University will not normally issue a CAS to support an application from inside the UK where you are required to demonstrate funds but cannot provide satisfactory evidence that you meet the financial requirement.
The current fee to extend or switch to a Student visa from inside the UK is £558.
You will normally also need to pay the Immigration Health Surcharge (IHS).
The current discounted IHS rate for students is £776 per year of immigration permission. The amount you actually pay depends on the total period of immigration permission you will receive, rather than simply the length of your course.
For example, Student permission normally includes additional time before and after your course.
Visa application fees and IHS rates can change, so check gov.uk immediately before submitting your application.
You must apply online through gov.uk.
As part of the application you will normally:
At the University of Gloucestershire, International Student Services will support you through this process.
Once we have completed our checks and are satisfied that you are eligible to apply from inside the UK, we will issue your CAS and arrange a one-to-one appointment with you to help you complete and submit your Student visa application.
Your CAS will normally be retained by International Student Services until your appointment so that we can confirm that you are ready to apply and that the information used in your application is correct.
You must be physically in the UK when you submit your Student visa application.
Do not submit your application independently before your appointment, unless International Student Services has confirmed that you should do so.
As part of your Student visa application, UKVI will tell you how you need to prove your identity.
Depending on your circumstances, you may either:
If you are required to attend a UKVCAS appointment, this will normally involve providing your fingerprints and photograph.
During your one-to-one Student visa application appointment, International Student Services will help you identify which process applies to you and explain the next steps.
If a UKVCAS appointment is required, you will need to follow the instructions provided after your online application has been submitted.
You should not book or attend a biometric appointment before submitting your online Student visa application unless UKVI specifically instructs you to do so.
Possibly. UKVI can ask Student visa applicants to attend an interview before making a decision.
A credibility interview may include questions about:
You should answer questions naturally, honestly and in your own words.
The purpose is not to test whether you have memorised prepared answers. UKVI will consider whether you are a genuine student and whether the information you have provided is credible. Your ability to communicate in English may also be considered.
If UKVI asks you to attend an interview, you should follow the instructions carefully. Failure to attend without a satisfactory explanation may affect your application.
It is important to take your UKVI credibility interview seriously and prepare carefully. An unsuccessful credibility interview is one of the most common reasons for a Student visa application to be refused. If UKVI is not satisfied, on the balance of probabilities, that you are a genuine student, your visa application must be refused. You should therefore make sure that you understand your course and university, can clearly explain your reasons for choosing to study in the UK, and answer all questions honestly and in your own words.
UKVI currently advises that Student visa applications made inside the UK are usually decided within eight weeks.
Some applications can take longer. For example, UKVI may need additional time if:
You may be offered the option to pay for a faster decision.
Priority services may be available for an additional fee, but availability is not guaranteed. You will be told whether a faster service is available when you apply.
If you’re eligible, you can choose the Priority service when you apply. You’ll need to pay £500 in addition to the application fee. Using the Priority service means you’ll usually get a decision within five working days.
Alternatively, if you’re eligible, you can choose the Super Priority service when you apply. You’ll need to pay £1,000 in addition to the application fee. How quickly you get a decision depends on when you prove your identity, but you’ll normally get a decision by the end of the next working day, or two working days if your identity is proved on a weekend or bank holiday.
Only certain Student visa holders can bring dependants under the Student route.
For courses starting on or after 1 January 2024, your dependants may be able to come to the UK or stay longer in the UK if you are:
There are also provisions which may allow existing Student dependants to extend their permission in certain circumstances.
Your dependant must also be eligible to make their application from inside the UK.
They cannot normally switch to Student dependant permission from inside the UK if they currently have, or were last granted, permission as a Visitor, Short-term Student, Parent of a Child Student, Seasonal Worker or Domestic Worker in a Private Household.
This depends on how long they have been living in the UK with valid immigration permission.
If your partner or child has been living in the UK with valid immigration permission for at least 12 months on the date of their application, they will normally meet the financial requirement automatically and will not need to demonstrate maintenance funds.
If they have been in the UK for less than 12 months, they will normally need to meet the Student dependant financial requirement.
Different evidence arrangements may also apply to certain nationalities under the differential evidence requirements, but this does not remove the requirement to actually have the necessary funds.
For University of Gloucestershire students, each dependant currently needs £680 for each month of Student immigration permission, up to a maximum of nine months.
This gives a current maximum of £6,120 for each dependant.
This is required in addition to the money you need for your own course fees and living costs.
Where financial evidence is required, the funds must normally have been held for at least 28 consecutive days. The final date of that period must normally be no more than 31 days before the dependant visa application is submitted.
A dependant who has been living in the UK with valid immigration permission for at least 12 months will normally meet the financial requirement automatically.
Please refer to our Student route financial requirements webpage for further information.
The exact documents required will depend on their circumstances.
A dependant will normally need:
If your dependant has been living in the UK with valid immigration permission for at least 12 months, they will normally meet the financial requirement automatically.
Examples of relationship evidence include marriage certificates, civil partnership certificates and birth certificates. UKVI may request additional evidence where necessary to establish that a relationship is genuine and continuing.
Each dependant should follow the document checklist generated as part of their own application.
Each eligible dependant must submit their own online visa application.
If your dependants are already in the UK, they can normally apply to extend or switch their immigration permission at the same time as you, or make a separate application before their current immigration permission expires. However, not all immigration categories permit switching from within the UK.
They’ll need your application number – you get it when you apply. This number is called a Global Web Form (GWF) or a Unique Application Number (UAN). You’ll find it on emails and letters from the Home Office about your application.
The application should identify you correctly as the main Student visa holder or applicant.
Your dependants will also need to provide supporting documents and verify their identity, including attending a UK Visa and Citizenship Application Services (UKVCAS) appointment to provide biometric information where required.
Each dependant must pay a separate visa application fee.
The current Student dependant application fee for applications made inside the UK is £558 per applicant.
Dependants will also normally need to pay the Immigration Health Surcharge. The discounted dependant IHS rate is currently £776 per year of immigration permission.
The exact IHS amount depends on the length of immigration permission being granted.
Visa application fees and IHS rates can change, so check gov.uk immediately before submitting your application.
A child born in the UK does not automatically become a British citizen simply because they were born here.
A baby born in the UK can remain in the UK without immediately making an immigration application. However, you should normally apply for Student dependant permission for your child if you want them to travel outside the UK and return, as they will need appropriate immigration permission to re-enter the UK.
You will normally need:
If you submit a valid Student visa application before your current immigration permission expires, you can normally remain lawfully in the UK while UKVI considers your application, even if your existing visa expires before you receive a decision.
This is known as section 3C leave.
While section 3C leave applies, the conditions attached to your previous immigration permission normally continue. For example, if your previous visa allowed you to work subject to particular restrictions, those restrictions will normally continue while your application is pending.
Section 3C leave can end if you take certain actions, including withdrawing your application or leaving the UK.
If you submitted a valid Student visa application before your previous immigration permission expired, your existing permission can normally be extended automatically under section 3C of the Immigration Act 1971 while UKVI considers your application.
This means you normally remain lawfully in the UK even though the expiry date shown on your previous visa has passed.
The conditions attached to your previous immigration permission normally continue during this period.
You should keep evidence that you submitted your Student visa application before your previous visa expired.
Do not assume that section 3C protects you if your application was submitted after your previous permission expired or if the application is invalid.
You should not travel outside the Common Travel Area while your application is pending.
The Common Travel Area consists of:
If you leave the Common Travel Area before UKVI has decided your in-country Student visa application, the application will normally be treated as withdrawn. This applies even if you still have your passport.
If you urgently need to travel, contact International Student Services before making arrangements, as withdrawing or abandoning an application can have significant consequences for your immigration status.
Potentially, but only in certain circumstances and with the University’s agreement.
Home Office Student sponsor guidance allows a Student Sponsor to permit a student to begin a new course before UKVI has decided their application where the relevant requirements are met.
These include that:
Additional requirements can apply depending on whether you are continuing a new course at the University of Gloucestershire, or moving to us from a different Student sponsor.
Starting your course before UKVI has granted your new Student visa is at your own risk, because your application could subsequently be refused. You must therefore not assume that you can enrol or start your new course while your application is pending. The University will confirm whether you are permitted to do so.
If you submitted a valid application before your previous immigration permission expired and section 3C leave applies, the conditions of your previous immigration permission normally continue while UKVI considers your application.
This includes your existing work conditions, in which case you must continue to comply with the work conditions attached to your previous immigration permission until your new Student visa is granted.
Once your new Student visa is granted, the work conditions attached to your new permission apply instead.
You can ask UKVI to withdraw a Student visa application before it has been decided.
However, withdrawing an application made from inside the UK can have serious immigration consequences.
If your previous immigration permission has already expired and you are relying on section 3C leave, withdrawing your application will normally bring that section 3C leave to an end. This could mean that you no longer have permission to remain, study or work in the UK.
Do not withdraw an application simply because you need to travel without first obtaining advice.
In the first instance, please contact International Student Services to advise us of the refusal. It’s important to also upload a copy of your visa refusal notification to CAS Shield, so that we can review the reason for refusal and provide appropriate guidance. We will review the effect of the refusal on your immigration status and studies, and advise what options may remain available to you.
Administrative Review
Your refusal notification will tell you whether you can request an Administrative Review. An Administrative Review allows UKVI to reconsider certain immigration decisions where a caseworking error may have occurred.
For an application made inside the UK, an Administrative Review must normally be requested within 14 calendar days of receiving the decision.
While it is not an opportunity to submit a completely new application or simply disagree with the UKVI decision, the review focuses on whether UKVI made a specific caseworking error when applying the Immigration Rules or assessing the evidence originally submitted with your application.
It is important to note, even where an Administrative Review succeeds, there is no guarantee that the visa will ultimately be granted.
Once International Student Services have reviewed your visa refusal notification, we will advise whether we believe you have reasonable grounds to submit an Administrative Review and whether there is a strong prospect of the decision being overturned.
A refusal does not automatically mean that the University will issue another CAS.
We will need to consider:
You cannot continue with an Administrative Review and make a new visa application at the same time. If you submit another visa application while your Administrative Review is pending, the Administrative Review will be treated as withdrawn.
An eVisa is the digital record of your UK immigration status and the conditions attached to your permission. Successful Student visa applicants now receive their immigration status digitally, rather than relying on a physical Biometric Residence Permit (BRP) card.
Your visa decision will tell you how to access your eVisa through your UKVI account.
You should access your UKVI account and check your eVisa as soon as your application is granted. In particular, you should:
You can also use your UKVI account to prove your immigration status where required.
Please refer to our Online immigration status (eVisa) webpage for further information.
Check your eVisa as soon as your Student visa is granted.
You should check:
If you believe any information is incorrect, contact International Student Services and follow the appropriate gov.uk process for reporting an eVisa error.
Please refer to our Online immigration status (eVisa) webpage for further information.
If your application from inside the UK is successful, your new Student permission will normally start on the date UKVI grants your application. From that date, the conditions attached to your new Student permission apply. This means, for example, that any work conditions attached to your new Student visa replace the conditions attached to your previous immigration permission.
Check your eVisa carefully as soon as you receive your decision to confirm the start date and conditions of your new Student permission.
Your new Student permission will normally start on the date UKVI grants your application, and normally includes additional time after your course.
The end date of your Student visa will depend on the length of the course. It will include a ‘wrap-up period’ after the completion of your course, during which you can remain in the UK for travel, work, leisure, to attend your graduation, or to make a new visa application.
| Type and length of course | Period granted before course start date | Period granted after course end date |
|---|---|---|
| Course lasts 12 months or more | From date application granted | Four months |
| Course lasts between six and 12 months | From date application granted | Two months |
| Pre-sessional course of less than 6 months | From date application granted | One month |
| Course is less than 6 months long and is not a pre-sessional course | From date application granted | Seven days |
Check the dates shown on your eVisa as soon as your visa is granted.
If you believe the length of permission you have been granted is incorrect, contact International Student Services and follow the appropriate gov.uk process for reporting an eVisa error.
Please refer to our Online immigration status (eVisa) webpage for further information.
Your right to work depends on the conditions attached to your Student visa and the course you are studying.
Students studying a full-time course at degree level or above are normally permitted to work:
The weekly limit applies across all jobs combined, not separately to each employer.
There are also restrictions on the type of work you can undertake. Student visa holders must not normally:
You are responsible for complying with the work conditions attached to your visa. Your employer is also responsible for carrying out an appropriate right-to-work check.
Postgraduate students should be particularly careful when considering whether they are in term-time. A dissertation or research period, or an absence of taught classes, is not automatically a University vacation.
Please refer to our Working in the UK webpage for further information.
While a valid in-time Student visa application is pending and you have section 3C leave, the conditions attached to your previous immigration permission normally continue. Your new Student visa conditions do not normally apply simply because you have submitted the application.
Once UKVI grants your new Student visa, the conditions attached to your new Student permission take effect.
For example, if your previous immigration permission gave you different work rights from those attached to your new Student visa, you must follow:
Check your eVisa as soon as your application is successful so that you understand the work conditions which now apply to you.
