UK departure checklist — CAS to landing

CAS, the 28-day fund rule, IHS payment, eVisa and UKVI account setup, TB test, ATAS, what to hand-carry, and Border Force questions.

Work backwards from your CAS start date

The UK Student visa process has a strict, sequential order — offer, CAS, funds, IELTS UKVI, TB test, then the visa application itself. Miss the order and you lose weeks. All fees and fund thresholds below are approximate and change — always verify current figures at gov.uk/student-visa before you rely on any number here. £1 ≈ ৳155 for planning purposes.

Step 1: Unconditional offer and deposit

Your conditional offer becomes unconditional once you've met academic and English-language conditions and paid any required tuition deposit. Only after this can the university issue your CAS (Confirmation of Acceptance for Studies) — the single most important document in the entire process, as your visa application cannot proceed without it.

Step 2: The 28-consecutive-day maintenance fund rule

This is the single most common reason for visa refusal

You must show a bank balance that meets or exceeds the required amount continuously for a minimum 28-consecutive-day period, and the closing balance on the account on any day in that window must never dip below the required threshold — even for one day. The balance must be checked and dated no more than 31 days before you submit your visa application. Current published figures are approximately £1,529/month for courses in London and £1,171/month outside London, capped at a maximum of 9 months of living costs even for longer courses — but these figures change, so verify the exact amount for your course length on gov.uk/student-visa before relying on it.
ItemApprox. amount (2026)In taka (£1≈৳155)
Living costs — London course, per month (max 9 months)£1,529৳2,36,995
Living costs — outside London, per month (max 9 months)£1,171৳1,81,505
Tuition — first year's fees minus any deposit already paidAs shown on your CASConvert at the current rate

If a parent or sponsor is providing the funds, the money must have been held by them (or you) for the same unbroken 28 days, and specific rules apply to which relatives can act as a financial sponsor and what evidence is needed. Read the current sponsor rules on gov.uk/student-visa carefully — this is where many otherwise-strong applications fail.

Step 3: IELTS UKVI (SELT) and the TB test

  • Take IELTS for UKVI, not the general/academic test

    The Home Office only accepts an approved Secure English Language Test (SELT) — check your university's exact requirement, as some accept a standard IELTS Academic score for admission but the Home Office still requires SELT-approved evidence for the visa in certain cases.

  • TB test at an IOM-approved clinic in Dhaka

    Mandatory for all Bangladeshi Student visa applicants. The test must be done at a Home Office-approved clinic — currently run via IOM in Dhaka — and the certificate is valid for 6 months from the test date. Book early; slots fill up around intake season.

  • ATAS certificate for sensitive postgraduate courses

    If your postgraduate course is in certain science, engineering or technology fields (check the current ATAS subject list), you need an Academic Technology Approval Scheme certificate before you can apply for your visa — this can take several weeks, so apply for it as soon as your offer is unconditional.

Step 4: Pay the visa fee and Immigration Health Surcharge upfront

FeeApprox. amountIn taka (£1≈৳155)When paid
Student visa application fee£524৳81,220At the time of online application
Immigration Health Surcharge (IHS)£776 per year of your course৳1,20,280 per yearPaid upfront, in full, for your entire course length, during the application
Biometric enrolmentIncluded in the visa feeAt your VFS Global appointment in Dhaka

The IHS is charged for the full length of your course in one lump sum at the time of application, not annually — this often comes as a surprise, so budget for it alongside the visa fee itself. Once paid, it entitles you to use the NHS on broadly the same basis as a UK resident.

Step 5: Biometrics, decision waiting times, and the digital eVisa

  1. 1

    Book your VFS Global biometric appointment in Dhaka

    After submitting the online application and paying the fee and IHS, you'll book a slot at the VFS Global visa application centre to give fingerprints and a photo, and submit supporting documents.

  2. 2

    Wait for the decision

    Standard processing is typically a few weeks, but always check the current published waiting time on gov.uk before assuming a date — priority services may be available for an extra fee.

  3. 3

    You will not receive a BRP card

    Since the shift to digital immigration status, most students no longer get a physical Biometric Residence Permit. Instead, your immigration status is stored digitally and you access it through a UKVI account (view and prove your immigration status online) — set this account up and check your eVisa details as soon as your visa is granted.

  4. 4

    Screenshot and print your eVisa share code

    Even though your status is digital, carry a printed copy of your decision letter and a generated share code — useful at the UK border and when registering with a GP, bank or landlord.

What to hand-carry — never in checked luggage

  • Passport with visa decision letter / eVisa confirmation

    The single most important document in your bag.

  • CAS letter (printed)

    Border Force may ask to see it even though it's digitally linked to your application.

  • Original academic transcripts and certificates

    Sealed university envelopes where provided.

  • TB test certificate

    Keep a printed copy even though the result is on file.

  • Proof of accommodation and university contact details

    Address of your hall or first landlord, plus the international office's contact.

  • Initial funds — cash and cards

    Enough for the first few weeks before your UK bank account is open.

Border Force questions on arrival

At UK immigration, an officer may ask about your course, university, how you're funding your studies, and your accommodation arrangements. Answer simply and consistently with your visa application — carry your CAS, offer letter and proof of funds summary in your hand luggage in case you're asked to show them.

First week on campus

  1. 1

    Register with a GP

    Do this in week one even if you feel healthy — registration itself can take time, and you'll need it if you fall ill later.

  2. 2

    Open a UK bank account

    Bring your passport, eVisa/share code, university enrolment letter and proof of address — see our banking guide for which banks are easiest for new international students.

  3. 3

    Apply for a National Insurance number if you plan to work

    See our part-time jobs guide — apply at gov.uk/apply-national-insurance-number as soon as you have a UK address.

  4. 4

    Complete university enrolment and ID card collection

    You cannot access most campus services, including the library and student job listings, until enrolment is confirmed.

Verify at the official source

Fees, fund thresholds, IHS rates, ATAS subject lists and processing times change. Confirm current figures and rules at gov.uk/student-visa, gov.uk/apply-national-insurance-number and ukcisa.org.uk before making any decision based on this guide.
