Here’s a clear, no-agent, step-by-step guide for applying for a UK visa in 2025—from Nigeria or anywhere else—plus the documents, fees, and pro tips you’ll need.

1) Pick the right visa (start on GOV.UK)

All UK visa applications begin on the official site. Use the “Compare visas” pages to choose: Visitor, Student, Skilled Worker, Family, etc., then click through to the application for your category.

• Standard Visitor (tourism, short business, medical): apply online via GOV.UK.

• Student: you’ll need a CAS (Confirmation of Acceptance for Studies) from a licensed school before you apply.

• Skilled Worker: you’ll need a job offer from a licensed sponsor and a Certificate of Sponsorship (CoS).

2) Check health, TB, and English rules early

• If you’ll stay over 6 months and you’ve lived in Nigeria (or another listed country), you must get a TB test from a Home Office-approved clinic and upload the certificate with your application.

• Some visas (e.g., Student, Skilled Worker) require proof of English and specific supporting documents listed on GOV.UK pages for that visa.

3) Gather your documents (typical set)

Exact lists vary by visa; GOV.UK gives category-specific checklists. For a Visitor visa, for example, see the official “supporting documents” guide. 
Common items:

• Valid passport (with a blank page) and any old passports.

• Evidence of purpose of trip (itinerary, invitation, conference proof, treatment letters).

• Funds & ties (bank statements, employment letter, property/family ties at home).

• Visa-specific items (e.g., CAS for Student; CoS for Skilled Worker). TB certificate if required.

4) Apply online on GOV.UK

Create/Sign in to your UKVI account and complete the online form for your visa. You’ll pay the application fee here, and—if your visa requires it—the Immigration Health Surcharge (IHS).

About IHS: Most visas over 6 months require you to pay the IHS during the application; you’ll need your course dates (Student) or CoS dates (Skilled Worker) to calculate the amount.

5) Book biometrics & upload documents

After submitting the form, you’ll be directed to the correct visa application centre partner for your country (typically VFS Global or TLScontact) to:

• Book a biometrics appointment (fingerprints + photo).

• Upload your supporting documents (or pay to have them scanned at the centre).

6) Attend your appointment

Bring your appointment confirmation, passport, and any documents you didn’t upload. Staff will capture biometrics and collect any required documents. (VFS/TLS instructions are shown during booking.)

7) Wait for a decision

Processing times vary by visa and country and can change through the year. You’ll see current estimates on GOV.UK pages for your visa; some locations offer Priority or Super Priority services for an extra fee (availability varies).

8) Your result, passport, and travel

• If granted outside the UK, you’ll get a decision notice and a visa vignette (sticker) in your passport or instructions about collecting it, then travel to the UK. (Collection/return is managed by VFS/TLS.)

• The UK is moving to eVisas (digital status) and phasing out physical cards; by 2025 most statuses are digital. Keep an eye on official updates and set up your eVisa account when invited.

  Note: some organisations have had teething issues accepting eVisas as ID; always carry your passport and be ready to share your digital status when needed.

Nigeria-specific notes (since you’re in Lagos time zone)

• TB testing must be at an approved clinic (IOM/approved list) before you apply if your stay exceeds 6 months; book early due to appointment demand.

• Document handling and appointment booking in Nigeria is through VFS Global; you upload documents when scheduling or use paid submission services at the centre.

Common mistakes to avoid

• Using non-approved TB clinics → certificates are rejected.

• Uploading incomplete financial or purpose evidence → leads to refusals, especially for visitors. Applying without CAS/CoS for Student/Skilled Worker. Ignoring IHS → most longer visas require it at application time. Relying on unofficial websites → always start on GOV.UK and only use VFS/TLS booking links from there.
