The Ultimate Guide to CAS Letter UK for Indian Students 2026

End-to-End Application Support

Counselor insight: Many Indian students assume the offer letter is enough to start the visa process. It is not. The offer letter confirms your place at the university; the CAS letter UK for Indian students formally sponsors your visa with UKVI. Confusing the two is one of the most common reasons students miss their visa application window.

CAS Letter UK vs Offer Letter vs Unconditional Offer: Know the Difference

DocumentIssued byWhenPurpose
Conditional offer letterUK universityAfter application reviewOffers a place subject to conditions (results, IELTS score)
Unconditional offer letterUK universityAfter all conditions are metConfirms your place with no remaining conditions
CAS letter in UKUK university (via UKVI system)After deposit payment + document verificationFormally sponsors your UK student visa application

The CAS letter in UK is the last document in this chain. You cannot request it until you hold an unconditional offer. The unconditional offer cannot come until you have met every condition, including your IELTS or PTE score and your final academic results.

What Information Appears in Your CAS Letter UK for Indian Students

Your CAS statement contains the exact details UKVI will use to assess your visa application. Any mismatch between your CAS letter UK for Indian students and your visa form triggers a query or refusal.

FieldIndia-specific note
Full nameIt must match your passport exactly, including middle names and spelling
Date of birthChecked against passport; discrepancies cause immediate rejection
Passport numberConfirm your current passport is the one registered with the university
CAS reference number14-digit alphanumeric code; valid for 6 months from issue date
Course title and levelUG (RQF Level 6) or PG (RQF Level 7). Determines visa duration
Course start and end datesThese directly determine how long your visa is granted for
Total course feesFull first-year tuition, not just the outstanding balance
Amount paid to dateDeposit amount: UKVI calculates your remaining balance from this
English proficiency evidenceYour IELTS/PTE score as submitted must meet the visa minimum
Previous qualificationsYour Indian degree/marksheets are accepted by the university
University Sponsor Licence Number (SLN)Your CAS will show your university's UKVI Sponsor Licence Number. You can verify your university holds an active licence at the official Register of Licensed Sponsors on gov.uk before paying any deposit.
Accommodation details (if applicable)Some universities include paid university accommodation on the CAS. If your university accommodation deposit is listed here, UKVI may offset it against the maintenance funds you need to show.

Counselor insight: Check your CAS letter UK for Indian students the same day it arrives. If your name is misspelled, your passport number is wrong, or your deposit amount does not match your payment receipt, contact the admissions office immediately. Correcting an error requires the university to issue a new CAS, which resets your processing timeline.

How to Get the CAS Letter UK for Indian Students?

Getting your CAS letter in UK is a sequence. Each step unlocks the next.

Step 1: Clear your conditions and get an unconditional offer

Send your university whatever they are waiting on: final marksheets, IELTS certificates, or any other outstanding condition. For most Indian students graduating in May-June 2026, this process occurs in late June or early July. Upload everything the same week your results arrive.

Step 2: Accept your offer and pay the tuition deposit

Accept the offer through the university portal and pay the deposit. Bank transfers from India take 3-5 working days to reach a UK account. Do not wait until the last day. A delayed payment is the most common reason Indian students miss the early CAS issuance window for September intake.

Step 3: Fill out the CAS request form

After your deposit clears, your university will open a CAS request form (sometimes called CAS Shield). You confirm your passport details, India address, finances, and course choice. Some universities trigger the process automatically; others need you to log in and start it yourself. Check your portal the same week you pay.

Step 4: Upload all your documents

You will need your passport scan, Class 10 and 12 marksheets, degree or provisional certificate, IELTS or PTE result, bank statements or loan sanction letter, and TB test certificate. If anything is missing, the university stops processing without notifying you. Should you not receive any response within 10 working days, it is advisable to follow up and request a document-by-document status check.

Step 5: Attend the pre-CAS credibility interview (if required)

A growing number of universities require this for Indian students, especially for postgraduate courses. It is a 10-20 minute video call covering why you chose this course, how it connects to your background, your career plans, and how your education is funded.

Be specific. "I chose MSc Data Science at Manchester because my BTech at Anna University covered ML fundamentals, and I want to move into AI product development." 

โ€œI want to gain more knowledge" does not. This is the step that most directly determines whether you receive your CAS letter in UK or face a delay.

See Pre-CAS interview questions and answers for a full prep guide.

Step 6: Receive and check your CAS statement

Your university registers the CAS in the UKVI system and emails you a PDF with your 14-digit CAS number. Before you submit your visa application, check your name, date of birth, passport number, course dates, and fees paid. If anything is wrong, flag it to admissions the same day.

Counselor insight: If too many students from a university get visa refusals, their sponsor license comes under UKVI review. This is why some universities run a more thorough check before issuing the CAS letter in UK. If your pre-CAS interview is not going well, the university will pause and ask for more documents. That is not a refusal. Keep the communication going and address what they ask for.

UK CAS Letter Processing Time and Validity 2026

Processing time for the CAS letter UK for Indian students ranges from 5 working days to 3-4 weeks, depending on the university and the time of year. June through August is peak CAS season for the September intake. During this period, most universities operate at full capacity, and delays of 3-4 weeks are common.

A CAS number is valid for 6 months from the date it is issued. You can use it to apply for your visa up to 3 months before your course starts. Once you submit a visa application using the CAS number, that number is spent: it cannot be reused. If your visa is refused, you need a new CAS from the university before you can reapply.

  • September 2026 intake: Expect CAS issuance from May to July 2026 for students who have already met all conditions. If your final results are coming in June, CAS issuance is realistically in July 2026, with visa applications in July-August and a September 2026 start.
  • January 2027 intake: CAS issuance typically runs October to November 2026. Visa application window: November-December 2026. 

See September and January UK intakes for a full comparison of both options.

Counselor insight: Most universities also have a finite annual CAS allocation from UKVI. Once their allocation is exhausted, they cannot issue further CAS letters until the next cycle. This is rare but real, and another reason to complete your deposit and document submission early rather than waiting until August.

CAS Letter UK for Indian Students Financial Requirements: What Indian Families Need to Show

This area is the section most guides get wrong or leave vague. Here is exactly what UKVI requires as of 11 November 2025, which applies to all 2026-2027 applications.

Maintenance funds (living costs):

LocationMonthly requirement9-month totalINR equivalent
Londonยฃ1,529ยฃ13,761Rs.17,83,160
Outside Londonยฃ1,171ยฃ10,539Rs.13,64,733

Exchange rate: ยฃ1 = Rs.129.49. Verify the current rate before finalizing your budget.

In addition to maintenance funds, you must also show the outstanding tuition fees from your CAS letter. For example, if your university charges ยฃ18,000 for the year and you have paid a ยฃ5,000 deposit, you must show ยฃ13,000 in outstanding fees on top of the maintenance amount.

A realistic total for a student starting an MSc outside London in September 2026:

  • Maintenance: ยฃ10,539 (Rs.13,64,733)
  • Outstanding tuition (example): ยฃ13,000 (Rs.16,83,370)
  • Total to show: ยฃ23,539 (Rs.30,48,103)

The 28-day rule: The full amount needs to sit in your account for 28 consecutive days. The closing balance on your bank statement must be dated within 31 days of the day you submit your visa application. If the balance dips even once during those 28 days, your application fails on financial grounds.

Whose account counts?

  • Your own savings or current account
  • Your parents' account, with a signed consent letter and your birth certificate
  • A sanctioned education loan letter from a recognised or government-backed lender, dated within 6 months of your application
  • Fixed deposits, only if the bank provides a letter confirming the funds can be liquidated immediately without penalty

Not accepted: Property valuations, salary slips, share portfolios, credit card limits, or mutual fund statements.

Counselor insight: A very common mistake among Indian students is moving money from several accounts into one just before the 28-day window starts. UKVI caseworkers are trained to flag sudden large deposits. If a significant sum lands in the account a few days before the window begins, expect a query or outright refusal. Start building the balance at least 35 to 40 days before your intended visa application date so that your 28-day window is clean. 

For scholarship holders, a letter from your university confirming the scholarship amount can reduce the maintenance funds you need to show. 

See scholarships for Indian students in the UK for options that may offset your financial requirement.

CAS Letter UK for Indian Students: Planning Calendar

March 2026CBSE/ICSE results: submit final Class 12 marksheets to universities if required
April-May 2026Degree final exams; accept conditional offers; prepare financial documents
May-June 2026University graduation results; convert conditional to unconditional offers; pay deposit
June-July 2026Submit CAS documents to university; complete the pre-CAS interview if required
July-August 2026Receive CAS letter in UK; begin 28-day bank balance window; apply for student visa

October 2026Apply for January 2027 intake: submit CAS documents to the university.
November-December 2026Receive CAS for January intake; apply for visa, and attend biometrics
January 2027January intake course begins

Counselor insight: Final-year students graduating in May-June 2026 with a September 2026 start should be honest with their university about their results timeline. Many universities will issue a provisional CAS based on predicted grades and upgrade it after results are confirmed. Ask your admissions office whether this is possible. Do not wait silently until results are out.

What to Do When Things Go Wrong: CAS Letter UK Delays, Refusals, and Errors

1. Your university has delayed or refused to issue the CAS letter UK for Indian students.

First, check whether all your documents have been verified. Universities typically do not notify students when a document check is still pending. They simply do not proceed. Email the admissions team directly with a document-by-document confirmation request.

If the university has explicitly refused the CAS on credibility grounds, request a written explanation. You can resubmit supporting material: a stronger personal statement, additional financial evidence, or a more detailed course-choice justification. If the refusal stands, you can apply to another university with a valid sponsor license, but your application timeline will be significantly compressed.

2. Your CAS letter in UK has expired before you could apply for a visa

A CAS is valid for 6 months. If your visa application has been delayed and the 6-month window is closing, you should immediately contact your university and request a new CAS. Universities can withdraw the old CAS and issue a new one. There is no fixed cost for the process at most universities, but some charge an administrative fee.

3. Your visa was refused after using the CAS

Once you submit a visa application with a CAS number, that CAS is spent regardless of the outcome. If your visa is refused, you need to request a new CAS from the university before reapplying. Read the refusal notice carefully: it will specify the exact grounds for refusal. Do not reapply until the specific weakness is addressed. 

For a full step-by-step on reapplying after refusal, see UK student visa application process.

4. There is an error on your CAS (name, dates, or fees)

Report the error to your admissions office on the same day. Do not submit a visa application with a CAS that contains errors. UKVI will cross-reference every detail against your passport and application form. A name discrepancy alone is sufficient grounds for visa refusal. The university will need to withdraw the original CAS and issue a corrected one.

Decision Framework by Student Situation

  • If you are a final-year BTech or BCom student graduating in May-June 2026 and waiting for results before your offer converts to unconditional: your CAS letter UK for Indian Students will realistically arrive in July 2026 at the earliest. Do not pay your deposit until you have results. Prepare your financial documents, TB test, and IELTS certificate now so you can move quickly once you confirm the results.
  • If you have received a conditional offer but your university has flagged your financial documents as insufficient: request a detailed explanation from the admissions office. If the issue is the 28-day rule, restructure your banking timeline. If the issue is the total amount, check whether a confirmed scholarship or education loan letter can supplement your bank balance. Do not resubmit the same documents.
  • If your visa was refused and your CAS has expired: request a new CAS from your university first. Do not apply for a new visa until you have a valid new CAS in hand. Most refusals are preventable on reapplication when the correct gap is identified.

3 Things to Do Right Now If You Are Waiting for Your CAS Letter in UK

  1. Start your 28-day bank balance window as soon as you accept your offer and pay the deposit. The maintenance funds and outstanding tuition fees must be in place for a continuous 28 days: this window cannot be improvised at the last minute. Identify whose account (yours or your parents') will hold the funds and begin building the balance now.
  2. Submit your CAS documents to your university at least 10-12 weeks before your course start date. For September 2026, that means July 2026 is your absolute latest. For January 2027, aim for October 2026. This window accounts for university processing time, any document queries, and the standard 3-week visa processing time at VFS Global India.
  3. Check every detail on your CAS statement the day it arrives, before submitting your visa application. A name spelling error, a wrong passport number, or an incorrect deposit amount requires the university to issue a new CAS, which resets your processing timeline by at least 1-2 weeks at a critical juncture.

Frequently Asked Questions About CAS Letter UK for Indian Students

  • How long does the CAS letter in UK take to process?

    ย It depends on the university and when you apply. Outside of peak season, most universities get the CAS letter UK for Indian students out within 5 to 20 working days once all your documents are verified. Between June and August, when everyone is scrambling for the September intake, that can stretch to 3 to 4 weeks. If you are aiming for September 2026, have your documents ready to submit by early July at the latest.

  • Is the CAS letter in UK the same as my offer letter?

    No, and this is one of the most common points of confusion. Your offer letter is the university telling you that you have a place. The CAS letter UK for Indian students is a completely separate document that the university generates in the UKVI system to formally sponsor your visa application. You cannot apply for a student visa using just your offer letter.

  • What is the CAS full form in the UK?

    CAS stands for Confirmation of Acceptance for Studies. It is an electronic record, not a physical letter you receive in the post. Your university enters your details into the UKVI system, which generates a unique 14-digit CAS number. That number is what you enter on your application form for a student visa.

  • How much money do I need in my bank account to get the CAS letter in UK?

    Your university checks your financials before issuing the CAS. For the 2026-2027 intake, UKVI requires living costs of ยฃ13,761 (Rs.17,83,160) for London or ยฃ10,539 (Rs.13,64,733) outside London, calculated over 9 months. On top of that, you need to show any outstanding tuition fees as stated in your CAS. All of it must sit in your account for 28 consecutive days.

  • Can I use my parents' bank account instead of my own?

    Yes, that is completely fine. Many Indian families do this type of transaction. You will need to provide a signed consent letter from your parent and your birth certificate to show the relationship. The 28-day rule applies to their account the same way it applies to yours, so plan the timing accordingly.

  • What is a pre-CAS interview, and do Indian students have to do it?

    The Pre-CAS interview is a short video call, usually 10 to 20 minutes, where someone from your university's admissions or visa compliance team checks that you are a genuine student. Not every university requires it, but it is increasingly common for Indian applicants, especially for postgraduate courses. You will be asked why you chose the course, how it connects to your previous studies, your career plans, and how your education is funded. Be specific and honest. Vague answers are a common warning sign.

  • What happens if my university refuses to issue the CAS letter in UK?

    They are required to give you a reason. The most common grounds are insufficient financial evidence, a credibility interview that did not go well, or documents that were incomplete or inconsistent. You can usually address the issue and resubmit. If the refusal stands after that, you can apply to a different UKVI-licensed university, though the delay will put pressure on your September 2026 timeline depending on where you are in the calendar.

  • My CAS letter in UK has expired. Can I get a new one?

    Yes. Get in touch with your university's international admissions or visa compliance team and ask them to issue a new CAS. They will withdraw the old one and generate a fresh one. One important point: if you already submitted a visa application using that CAS number, the number is spent even if your visa was rejected. You need a new CAS before you can reapply.

  • Does getting the CAS letter in UK mean my visa is guaranteed?

    No. The CAS letter UK for Indian students is a mandatory part of your application, but it does not secure the visa on its own. UKVI will still independently review your bank statements, English proficiency, immigration history, and whether they believe your primary purpose is to study. Students with a valid CAS letter are refused every year, most often because their financial documents do not meet the 28-day rule or because the visa officer is not satisfied with their genuine-student case.
