If you’re dreaming of landing in London or Manchester with a suitcase in one hand and a future‑ready degree in the other, there’s one non‑negotiable hurdle in your way: the UK student visa. The course, the city, and even the university come after this. No visa, no boarding pass, simple as that.
The good news? The process looks scarier on WhatsApp forwards than it actually is. Once you understand the role of the CAS letter UK, visa requirements UK, and the timelines, it turns into a predictable checklist instead of a mystery.
Below is a straight‑talk, Indian‑friendly guide that you can literally use as your visa prep blueprint for 2026.
Step 1: Offer & CAS – The entry tickets
You can’t even touch the UK student visa form until your university pushes one crucial document into your inbox: the CAS.
What is CAS?
The Confirmation of Acceptance for Studies is a digital document generated by your university after you accept the offer and meet its conditions. It carries: course details, start/end dates, fees, and your unique CAS number.
- Issued only after you have an unconditional offer and usually after paying the initial deposit.
- Typical processing time: 5–20 working days, sometimes up to 3–4 weeks in peak season.
- Valid for 6 months and can be used only once for a visa application.
In short: no CAS, no UK student visa. That’s why understanding the CAS letter UK, visa requirements UK, early in the process saves you from last‑minute panic.
Step 2: Know the core visa requirements UK expects
Once the CAS is sorted, you move to the official visa requirements UK immigration officers actually check. Think of it as a five‑point filter:
- Unconditional offer + CAS from a licensed student sponsor.
- Valid passport with enough blank pages.
- English proficiency (IELTS / PTE / other UKVI‑accepted tests, as per university/visa route).
- Financial proof for tuition + living costs for up to 9 months.
- Health & background checks – TB test for Indian applicants, clean record, Immigration Health Surcharge payment.
Most rejections happen because students underestimated this combination of a CAS letter UK, visa requirements UK – either funds weren’t held long enough, or details on the CAS and application didn’t match.
Step 3: Financials: maintenance & fees
This is where you have to be painfully precise.
a) Visa fees & IHS
Recent guides for 2026 applications show:
- Visa application fee: about £490–£524 (standard service).
- Immigration Health Surcharge (IHS): roughly £776 per year of your course.
Always re‑check these amounts just before paying—they’ve been creeping up almost every year.
b) Maintenance funds (living costs)
From 2025 onwards, the Home Office has sharply increased the monthly maintenance thresholds.
For applications in the 2025–26 window, you typically need to show:
- London: roughly £1,334–£1,529 per month (up to 9 months).
- Outside London: roughly £1,023–£1,171 per month (up to 9 months).
On top of this, you must show any unpaid tuition for the first year (e.g., total £20,000, deposit paid £4,000 → show the remaining £16,000).
Key rules:
- Money must sit in the account for at least 28 consecutive days.
- The end of that 28‑day period must be no more than 31 days before you submit the visa application.
One wrong date on a bank statement and your otherwise‑perfect profile can be refused.
Step 4: Filling out the UK student visa application
Once funds and documents are lined up, you finally move to the online form.
Typical flow (for the Student Route):
- Create an account on the official UKVI portal and start the UK student visa application.
- Enter your CAS number, course details, and personal info exactly as on the CAS.
- Declare your financials and upload supporting documents (or carry them to VFS, depending on the mode).
- Pay the visa fee + IHS online.
- Book your biometrics appointment at a VFS centre in India and attend with originals for verification.
From your biometric data, standard decisions usually take around 3 weeks, while priority options can shrink it to about 5–7 working days, at extra cost.
Step 5: Smart timelines so you don’t cut it too close
If you want a calm departure instead of a last‑minute scramble:
- Universities often set a CAS deadline 6–8 weeks before the course start. Miss that, and they can push you to the next intake.
- CAS issuance itself can take 5–20 working days, longer in June–August.
- Add 3–4 weeks for visa processing (standard route).
Realistically, you should:
- Finish university applications 6–8 months before intake.
- Aim to receive your CAS at least 10–12 weeks before the course start date.
- File your visa as soon as your funds hit the required 28‑day mark and your documents match all the visa requirements UK lists.
That way, you leave a buffer for any document query or additional checks.
