UK Student Visa Timeline: How Long It Really Takes
UKVI's published processing time is approximately three weeks from the date you submit biometrics at a VFS Global centre — but for African applicants that decision window is only the final stage of a process typically running ten to fourteen weeks, mainly because of the TB test requirement, which must be completed first, and the 28-day financial evidence rule.
The Full Timeline at a Glance
| Stage | What happens | Typical duration |
|---|---|---|
| 1. University offer → unconditional offer | Meet all conditions (English, deposit, etc.) | 1–8 weeks depending on your situation |
| 2. Book and complete TB test | Book appointment at approved IOM clinic; attend; receive certificate | 2–4 weeks (appointment + results) |
| 3. Open / prepare financial evidence | Ensure correct funds are in place; 28-day hold begins | 4 weeks (the hold itself) + set-up time |
| 4. Receive CAS from university | University issues CAS reference; check all details | 1–3 months before course start (university-dependent) |
| 5. Complete online visa application | Fill in on gov.uk; pay £558 fee + IHS upfront | 1–3 hours |
| 6. Book and attend VFS appointment | Submit biometrics and supporting documents at VFS Global centre | Same day or up to 2 weeks wait for appointment |
| 7. UKVI decision | Decision issued; eVisa linked to your UKVI account | ~3 weeks |
| 8. Travel to UK | Arrive on or after the visa start date | — |
| Minimum realistic total | Stage 1 → Stage 8 | 10–14 weeks |
Stage 1: From Offer to Unconditional Offer
Your UK Student visa can only be applied for once you have a valid CAS, and a CAS is only issued after you hold an unconditional offer. If your offer is conditional (pending IELTS, final exam results, or a deposit), the visa clock does not start until those conditions are cleared.
Do not assume you can move from conditional offer to CAS in a week. Common delays:
- IELTS test results: booked dates can be several weeks out, and results take up to two weeks to arrive
- Final secondary school results: WAEC, KCSE, NSC results published on a fixed date — check when yours release relative to your course start
- Tuition deposit: some universities require a deposit of £1,000–5,000 before issuing a CAS; factor this into your cashflow
Practical step: Contact your university’s International Student Support or Admissions office as soon as you accept an offer and ask: “When will you issue my CAS, and what do I need to do first?”
Stage 2: TB Test — Book This First
All African applicants for a UK Student visa for a course longer than six months must complete a TB test at an approved clinic before applying (gov.uk/tb-test-visa).
Nigeria, Ghana, Kenya, South Africa, Uganda, Zambia and Zimbabwe are all on the required-countries list.
Key facts:
- The test is done at an approved IOM clinic in your country. Using a private clinic that is not on the Home Office’s approved list means your certificate will not be accepted.
- The test typically involves a chest X-ray. Results are usually available within one to two weeks of your appointment.
- The certificate issued is valid for six months from the test date.
- Approximate cost: £75–95 or local-currency equivalent (as of June 2026 — re-check at booking). This is paid directly to the clinic and is not refundable if your visa is ultimately refused for other reasons.
Why to book this first: Clinic appointment availability varies and can be a bottleneck. If you wait until your CAS is issued before booking the TB test, you risk a several-week delay between receiving the CAS and being able to apply. Book the TB test as soon as your offer letter is confirmed and you know the course will be more than six months long.
Stage 3: The 28-Day Financial Hold
The financial evidence rule requires that the required maintenance funds — £1,529/month for London (maximum £13,761) or £1,171/month outside London (maximum £10,539) — plus the first year’s tuition fees as stated on your CAS, must be held continuously for 28 consecutive days, with that 28-day period ending no more than 31 days before your visa application date.
This means you cannot “show” the money on application day. You need to plan the 28-day window in advance:
- Decide on your application date
- Count back 31 days — that is the latest your 28-day window can end
- Count back a further 28 days — that is when the window must start
- Ensure the correct total is in the account on every day within that window
If funds dip below the threshold at any point — even by a small amount, even for one day — the hold is invalid. Transaction records will show this.
Practical note: Coordinate the 28-day window so it overlaps with or follows the issuance of your CAS. You need the CAS to complete the online application; you need the financial hold to have ended no more than 31 days before you submit.
Stage 4: Receiving Your CAS
Your university will issue the CAS typically one to three months before your course start date. Some institutions set a specific CAS-issue date for all international students (for example, six weeks before the September intake).
The CAS is a reference number in your UKVI account. Before you do anything with it, check:
- Your full name exactly as it appears on your passport (including middle names if any)
- Your date of birth
- Your passport number
- The course title, start date and duration
- The tuition fee stated (this must match what is on your fee letter)
Any error in these fields requires the university to reissue the CAS. Do not submit your visa application until you are certain every field is correct.
Stage 5: The Online Application
Once you have your CAS, your TB test certificate, and your 28-day financial window is complete or running:
- Go to gov.uk/student-visa/apply-online and create or log into your UKVI account
- Complete the online form (your CAS reference, personal details, travel history, declaration)
- Upload supporting documents (financial evidence, TB certificate, English proof, passport)
- Pay the £558 visa application fee and the Immigration Health Surcharge (£776/year × the full visa length, paid upfront). For a three-year course, the IHS alone is £2,328 — paid at this stage, before you receive a decision
- Book your VFS Global appointment
You apply from outside the UK (as a new student). The application is submitted online; the VFS appointment is for your biometrics.
Stage 6: VFS Global Appointment
VFS Global is UKVI’s visa application centre operator in Africa. Note: TLScontact is no longer operating UK visa centres — do not use old TLS booking links.
At the VFS appointment you submit fingerprints and a photograph. You may also deposit your passport if required. For most African applicants, the VFS appointment is booked online through the VFS website for your country, and appointment slots can fill up — especially in peak months (June–September for September intake students).
Book your VFS appointment as early as possible. If you are aiming for a September course start, appointment availability can be tight in July and August.
Stage 7: UKVI Decision
The published decision time is approximately three weeks from the date you submit biometrics. In practice, straightforward applications frequently come in closer to two weeks; complex cases or applications submitted during peak season may take slightly longer.
UKVI does not provide a tracked status update beyond a basic “in progress” flag. Priority visa services are available at VFS for an additional fee if you need a faster decision.
Once approved, your visa is issued as an eVisa — linked to your UKVI account. Physical Biometric Residence Permit (BRP) cards have been phased out. You share your eVisa via a share-code with anyone who needs to verify your status.
Stage 8: Arriving in the UK
Your Student visa has a start date. You cannot enter the UK before that date. The standard rule is that you may enter:
- Up to 1 month before your course start date if the course starts on 1 January or after
- Up to 1 week before if the course starts on 1 September, 1 October or 1 November (common for UK September intakes — confirm the exact allowance for your course start date on gov.uk)
Arriving early is useful for accommodation, university registration and orientation. Plan travel accordingly.
Working Backwards: Planning Your October 2027 Start
If your course starts 1 October 2027, a working timeline looks like this:
| Action | Suggested date |
|---|---|
| Accept offer / clear conditions | By end of May 2027 |
| Book TB test | May or June 2027 |
| Complete TB test and receive certificate | June or July 2027 |
| Begin 28-day financial hold | Late June or early July 2027 |
| Receive CAS from university | July 2027 (check with your uni) |
| Submit online application + VFS appointment | July 2027 |
| UKVI decision received | August 2027 (~3 weeks after biometrics) |
| Travel to UK | September 2027 |
If any stage slips — IELTS retake needed, CAS delayed, VFS appointment slot not available — the buffer narrows quickly. Starting earlier than necessary is the only safe buffer.
Common Mistakes That Add Weeks
- Booking the TB test only after the CAS arrives (adds two to four weeks)
- Starting the 28-day financial hold before the CAS is issued, then the CAS arrives late and the 31-day window expires
- Uploading bank statements that are over a month old at the time of application
- Missing the VFS appointment and needing to rebook (new slot may be several weeks away)
- Discovering a CAS error after the application is submitted

Frequently asked questions
UKVI's published decision time for applications submitted from outside the UK is approximately three weeks from the date you submit biometrics. This is the processing time only — it does not include the TB test (required for African origins on courses over six months) or the 28-day financial hold before you can apply. Most African applicants should plan for a total timeline of ten to fourteen weeks from beginning preparations to holding their visa.
You can apply for your UK Student visa up to six months before the start date of your course. Applying this early is permitted but the visa will not be valid before the period allowed. You cannot apply before you have a valid CAS from your university.
The TB (tuberculosis) test is a mandatory requirement for all African origins applying for a UK student visa for a course longer than six months. The test must be done at an approved IOM clinic in your country. You book online, attend the clinic for the test (usually a chest X-ray), and receive a certificate typically within one to two weeks. The certificate is then valid for six months. Budget approximately £75–95 (or local-currency equivalent, as of June 2026) and book the appointment at least four weeks before you plan to apply.
A CAS (Confirmation of Acceptance for Studies) is a reference number issued by your licensed UK university sponsor once you have accepted an unconditional offer and met all pre-enrolment conditions (including English, deposit payment if required, and DBS check if applicable). Your university will issue it typically one to three months before course start. You cannot apply for your visa until you have the CAS — do not plan your timeline without first asking your university when they plan to issue it.
Yes, for courses longer than six months. Nigeria, Ghana, Kenya, South Africa, Uganda, Zambia and Zimbabwe are all on the Home Office's list of TB-test countries. The test must be at an approved clinic only — doing a TB test at a private clinic that is not on the Home Office approved list will result in your application being refused.
