From Offer to CAS: UK Study Steps Explained

CASofferconditionsdepositvisa preparationUpdated 9 July 2026 The path from receiving a UK university offer to getting your Confirmation of Acceptance for Studies, known as the CAS, follows a clear sequence of steps: you formally accept the offer, pay any required tuition deposit, meet all the conditions set out in your offer letter, and then the university issues your CAS. The CAS is the document that allows you to apply for a UK Student visa, so until you hold a valid CAS, you cannot submit your visa application. Each step has its own timeline, documentation requirements, and potential pitfalls. Knowing the sequence in advance helps you move through the process efficiently and avoid the most common delay: waiting until the last month before your course starts and discovering that a condition you thought was minor actually requires weeks of paperwork. This article walks through every step in the order they typically occur so you can plan your timeline from offer to visa application with confidence.

Step One: Accept Your Offer Formally

When a UK university makes you an offer, it is not yet a binding agreement. You must formally accept it, usually through the university’s application portal or, for undergraduate courses, through UCAS. Accepting an offer typically involves clicking an acceptance button, but some universities require a written acceptance statement or additional documentation at this stage.

Before you accept, read the full offer letter carefully. It contains the conditions you must meet, the deposit amount and deadline, the programme start date, and the tuition fee. If anything in the offer letter is unclear, contact the admissions team before accepting. Once you accept, you are committing to the terms set out in that letter.

For postgraduate applications, you may hold multiple offers and accept more than one provisionally, but this becomes expensive because each accepted offer may require a separate deposit. Most students accept one offer as their firm choice and, for undergraduate UCAS applications, may also hold an insurance choice with lower conditions.

Step Two: Pay the Tuition Deposit

Most UK universities require international students to pay a tuition deposit after accepting the offer. The deposit amount varies by institution and programme. Typical international student deposits for 2026/2027 entry range from £1,000 to £5,000, with some programmes, particularly those with high demand, asking for up to £8,000 or more. Some universities ask for a percentage of the first year’s tuition fee rather than a fixed amount.

The deposit serves two purposes. For the university, it confirms your commitment and reduces the number of students who accept offers but never enrol. For you, the deposit payment is a prerequisite for CAS issuance. Most universities will not begin the CAS process until the deposit has been received and cleared.

The payment method matters. Most universities accept international bank transfers, and many also accept payments through dedicated platforms like Flywire or Convera, which can reduce transfer fees and offer more favourable exchange rates. Check which payment methods your university accepts and factor in the processing time: international transfers can take three to five working days, or longer depending on the banking route.

The deposit deadline is typically four to eight weeks after you receive your offer, but this varies. If you need more time, ask the admissions team for an extension. Most will accommodate a reasonable request, particularly if you are waiting for scholarship decisions or loan approvals.

Step Three: Meet All Offer Conditions

Most UK university offers to international students are conditional, meaning you must meet specific requirements before the university will confirm your place unconditionally. The most common conditions are academic, English language, and documentary.

Academic conditions usually require you to achieve a specified final grade, GPA, or classification in your current qualification. If you are completing an undergraduate degree, the condition typically refers to your final overall result. If you are completing a secondary school qualification, it may specify particular subject grades. You meet the condition by submitting your final transcript or results certificate to the university.

English language conditions require you to achieve a specified score in an approved English language test, most commonly IELTS, TOEFL, PTE Academic, or a UKVI-approved Secure English Language Test (SELT) for visa purposes. Some universities also accept alternative evidence such as a previous degree taught in English or a specific grade in a relevant school qualification. Submit your test score report directly to the university, and check whether they accept electronic score delivery from the test provider, which is faster than sending a paper copy.

Documentary conditions may include submitting references, a personal statement, a portfolio, a research proposal, or evidence of relevant work experience. These are typically submitted during the application process, but some offers include them as outstanding conditions to be met after acceptance.

Meeting conditions involves sending the required evidence to the university, waiting for it to be verified, and receiving confirmation that each condition has been satisfied. This process can take several weeks, particularly during peak periods from June to August. Start gathering evidence as soon as you know what is required, and submit it well before any stated deadline.

Step Four: Complete Any Pre-CAS Checks

Before issuing the CAS, the university may run additional checks. These are not conditions of the offer but administrative steps the university must complete under its UKVI sponsor licence obligations.

Some universities conduct credibility interviews, either in person or by video call, to confirm that you are a genuine student with a clear understanding of the course you have accepted. This is not an assessment of your academic ability but a check that you have made a genuine and informed choice.

The university will also verify that your passport is valid and that your personal details match across all submitted documents. If your name on your passport differs from the name on your application or academic documents, you may need to provide additional evidence such as a marriage certificate or a name-change document.

If your programme requires Academic Technology Approval Scheme (ATAS) clearance, the university will ask for your ATAS certificate before issuing the CAS. ATAS applies to certain programmes in sensitive subject areas, primarily at postgraduate level in science, engineering, and technology fields. Check whether your programme requires ATAS early, as the clearance process can take four to six weeks or longer.

Step Five: Receive and Check Your CAS

Once you have met all conditions, paid your deposit, and passed any pre-CAS checks, the university issues your CAS. This is not a physical document but a unique reference number stored in the UKVI database. The university will send you a CAS statement, which is a document containing your CAS number and all the information the university has submitted to UKVI about you and your course.

When you receive your CAS statement, check every detail immediately. The most common errors include misspelled names, incorrect passport numbers, wrong course start and end dates, incorrect tuition fee amounts, and missing or incorrect details about how your English language requirement was met. Even a small error can cause your visa application to be delayed or refused.

If you find an error, contact the university immediately and ask for a correction. CAS corrections are usually quick to process, but they add time to your timeline. Catching errors early means you lose days rather than weeks.

The CAS is valid for six months from the date of issue. You must submit your Student visa application within this validity window. The CAS also becomes invalid if you use it for a visa application that is refused. If your visa application is refused, you must ask the university to issue a new CAS before you can reapply.

Step Six: Prepare Your Visa Application

With a valid CAS in hand, you can now prepare your Student visa application. The key documents you will need include: your valid passport, your CAS reference number, financial evidence showing you hold the required maintenance funds for the specified period, the ATAS certificate if applicable, your tuberculosis test results if required for your country of residence, and any documents listed on your CAS as having been used by the university to assess your application.

The financial evidence requirement is one of the most common sources of visa delays. For the 2026/2027 cycle, you must show you have held the required funds, including the first year’s tuition fee as stated on your CAS plus living costs of £1,334 per month for courses in London or £1,023 per month for courses outside London for up to nine months, for at least 28 consecutive days ending no more than 31 days before your visa application date. These figures are set by UKVI and are subject to change; always check GOV.UK for the current amounts before preparing your evidence.

Some students are exempt from the financial evidence requirement, depending on their nationality, the length of their course, and whether they have been in the UK with valid leave for at least 12 months. Check the differential evidence requirement on GOV.UK to confirm whether this applies to you before deciding not to prepare financial documents.

What This Means for Your Shortlist

The offer-to-CAS timeline is not the same for every university. Some universities issue CAS statements within a few days of conditions being met. Others take several weeks, particularly during the summer peak. When you are comparing offers or deciding which university to accept, ask about typical CAS processing times. A university with a consistently fast CAS process may give you more visa application buffer than one with known delays.

The deposit amount and refund terms also vary. A university asking for a £5,000 deposit with limited refund provisions is a different financial commitment from one asking for a £1,000 deposit with refunds available in specified circumstances. Understanding the deposit terms before you accept helps you make an informed commitment.

Finally, the conditions attached to your offer determine how much work remains between acceptance and CAS. An offer with conditions you can meet easily by sending a transcript is a different proposition from one requiring you to retake an English test and achieve a higher score while also completing your current qualification. Factor the difficulty of meeting conditions into your timeline and your risk assessment.

Before You Submit the Course-Options Form

• Have a clear timeline in mind: when your current qualification results will be available, when you plan to take or retake your English test, and when you need to submit your visa application.

• Research the deposit requirements and refund policies for each university on your shortlist. Know the deposit amount, payment deadline, and refund conditions before you accept an offer.

• Check whether your target programme requires ATAS clearance. If it does, build the four-to-six-week ATAS processing time into your overall timeline.

• Review your passport validity. Your passport should be valid for the full duration of your intended stay in the UK. If it expires during your course, plan to renew it before the visa process begins.

• Read the visa financial evidence requirements on GOV.UK. Understand how much you need to show, how long you need to hold the funds, and which types of accounts UKVI accepts.

FAQ

Q1: How long does it take to get a CAS after meeting all conditions?

Processing times vary by university and time of year. During quieter periods, some universities issue a CAS within a few working days. During the summer peak from June to August, it may take two to four weeks or longer. If you are approaching a CAS deadline, contact the university’s admissions or international office for an estimated timeline.

Q2: Can I apply for a student visa without a CAS?

No. The CAS reference number is a mandatory field in the Student visa application. UKVI will not process an application without a valid CAS, and the CAS must have been issued by a licensed student sponsor. There is no workaround or alternative to the CAS requirement.

Q3: What happens if I miss the deposit payment deadline?

If you miss the deposit deadline without having requested an extension, the university may withdraw your offer. However, most universities will grant a short extension if you contact them before the deadline with a reasonable explanation. After the deadline has passed, reinstating a withdrawn offer is at the university’s discretion and is not guaranteed.

Q4: Do I need to meet all conditions before the university issues the CAS?

Yes. UKVI rules require that the university confirm all conditions have been met before issuing a CAS for a Student visa application. The university must be satisfied that you are qualified and eligible for the course before it sponsors your visa application. Some universities may issue a CAS with outstanding conditions only if those conditions relate to ATAS clearance or similar external checks.

Q5: Can I use the same CAS if my visa application is refused?

No. If your visa application is refused, the CAS becomes invalid. You must ask the university to issue a new CAS before you can submit a new visa application. The university may charge an additional CAS issuance fee, and it will need to assess whether the reason for the refusal can be addressed in a new application.

Note: Visa rules, financial evidence requirements, and CAS processing policies referenced in this article are based on the UKVI Student route guidance applicable to the 2026/2027 cycle. UK immigration rules are subject to change. Always verify current requirements on GOV.UK and with your university’s international office before preparing your visa application.
