TL;DR
VFS Global is the outsourced UK visa partner used in most countries outside the UK. After paying the UKVI fee, you book a VFS appointment for biometrics and upload supporting documents online — strictly capped at 2 MB per file, the most restrictive UK visa upload limit. Bundle and aggressively compress before uploading.
How to upload documents to VFS Global
- Pay the UKVI visa fee through the gov.uk online application
- You're redirected to VFS Global for your country
- Choose a centre — typically your nearest major city
- Create your VFS Global account using the same email as your UKVI application
- Book a biometrics appointment — wait times vary 1-8 weeks by country and season
- Bundle your documents using our free Bundler in canonical UKVI order
- Compress aggressively — use our Compressor targeting 2 MB (the VFS limit). For safety margin, target 1.7 MB
- Upload through VFS portal — file by file or category by category
- Refresh after each upload to confirm files actually attached (silent failures are common at the limit)
- Attend the appointment — bring passport, appointment confirmation, and any optional supplementary documents
- Submit application — UKVI processes once biometrics are enrolled and documents are uploaded
What's different from UKVCAS
| Feature | VFS Global | UKVCAS |
|---|---|---|
| Where used | Outside the UK | Inside the UK |
| File size limit | 2 MB | 6 MB |
| Appointment cost | Standard usually free; premium tiers £30-£200 | Standard free; premium £100-£500 |
| Document scanning at centre | Available, paid | Available, paid |
| Wait time | 1-8 weeks (country-dependent) | 1-4 weeks |
| Standard processing | 3 weeks (Skilled Worker out-of-country) | 8 weeks (in-country) |
The smaller file limit and longer processing times make VFS the more challenging service for applicants — extra care with file sizes pays off.
How to hit 2 MB cleanly
The 2 MB cap is the practical bottleneck for most overseas applicants. Strategies:
Pre-compress source documents
Before bundling:
- Scan documents at 200-300 DPI (not 600+)
- Use greyscale for text-only documents (bank statements, employer letters)
- Phone photos: resize to 1200×1600 max, save at 80% JPG quality
- Convert HEIC to JPG before adding (UKVI rejects HEIC)
Bundle by category, not all-in-one
If your portal allows separate uploads per category (most VFS portals do):
- Upload passport documents in one ~1 MB PDF
- Upload financial in another ~1.5 MB PDF
- Upload qualifications, employment, etc. separately
Each PDF only needs to be under 2 MB individually — total can be more.
Compress with our tool
Our Compressor targets 2 MB specifically:
- Tries lossless structural pass first (often enough for text-heavy bundles)
- Re-renders pages at lower DPI/quality only if needed
- Stops at the lowest DPI that still produces legible text
Don't bundle what UKVI didn't ask for
VFS rejection for "missing documents" because the bundle was so big the actual evidence didn't fit is depressingly common. Stick to the official UKVI requirements:
- Run our Personalised Checklist — it filters out unnecessary documents
- Don't pad the bundle with family reference letters, photos UKVI didn't request, or duplicate evidence
Common VFS Global issues
Silent file rejection
Files over 2 MB silently fail to attach. The UI shows progress, completes, but the file doesn't appear in the document list. Fix: target 1.7 MB max. Refresh page after each upload. Re-upload anything missing.
Slow upload speed at the centre
If you opt for in-person scanning at VFS, the centre's WiFi is sometimes slow — uploads at the centre can take much longer than uploading from home. Upload before attending.
Premium service confusion
VFS Global offers many add-on services (premium lounge, scan-and-shred, courier delivery, copy printing). These are processed through VFS, not UKVI. Don't confuse them with UKVI's own priority/super-priority decision services (which are separate, paid through gov.uk).
Appointment cancellation
VFS occasionally cancels appointments due to capacity issues. Check email and the VFS portal a few days before. Reschedule promptly to keep your application on track.
Wrong country selection
When you pay the UKVI fee, you select your country of application. This determines which VFS centre you use. Once selected, changing requires contacting UKVI. Double-check before paying.
After VFS
Once biometrics are enrolled and documents are uploaded:
- VFS forwards your data to UKVI
- UKVI's stated processing time begins from this point (not from your visa application date)
- You'll receive the decision via email
- If granted, your immigration status appears in your gov.uk View and Prove account; physical BRP issue is being phased out
Standard UK overseas processing: 3 weeks for Skilled Worker, 12 weeks for Spouse/Family, 3 weeks for Visitor. Priority service cuts this to 5 working days; super-priority to next working day in many centres.

Common questions
- 01
What is VFS Global?
An outsourced visa service partner that runs UK visa application centres in most countries outside the UK. Provides biometrics enrolment, document scanning and submission services on behalf of UKVI. Not the same as TLScontact (used in some specific countries like France and Switzerland).
- 02
What's the VFS Global file size limit?
2 MB per file — significantly stricter than UKVCAS's 6 MB. The limit is enforced silently; oversized files don't attach with no error. Always compress to under 2 MB before uploading.
- 03
Do I need to upload documents before my biometric appointment?
Yes — VFS Global requires documents uploaded online before the appointment. You can pay extra for in-person scanning at the centre, but online upload before attending is faster and avoids extra fees.
