Catch tampered supporting documents before they reach the consulate.
Visa fraud rarely starts with the visa itself.
The most common form of visa fraud is the bundle of supporting documents that accompanies an application - fabricated bank statements, fake employment letters, doctored itineraries, and altered sponsorship letters. These documents are submitted in volume and reviewed under time pressure. TamperCheck verifies each one forensically, on digital PDFs and scanned hard copies alike.

The problem
What fraud looks like in visa & immigration
How it typically shows up, and the forensic signal that exposes each one.
Fabricated bank statements for financial proof
Applicants submit bank statements with inflated balances or added salary credits to meet the financial sufficiency threshold. Running balance plausibility, table row alignment, and PDF text layer analysis expose the manipulation.
Fake or altered employment letters
Employment letters are fabricated or edited to show higher salaries, different job titles, or false employers. Letterhead plausibility, font consistency, and physical stamp authenticity checks flag the forgeries.
Tampered travel itineraries and invitation letters
Flight bookings, hotel confirmations, and invitation letters are generated or altered to fabricate travel plans. Airline branding, booking reference format, and date plausibility are all analysed.

FAQ
Common questions about visa & immigration
Can TamperCheck verify physical stamps on immigration documents?
Yes. TamperCheck distinguishes between a genuine physical stamp - ink bleed, pressure variance, alignment imperfections - and a digitally placed overlay imitating one. This matters for visa supporting documents, which are frequently scanned or photographed hard copies rather than native digital files.
How does it handle documents submitted as phone photos rather than scans?
The forensic checks adapt to the input: native PDFs get full structural analysis (text layer, producer metadata, font embedding), while photos and scans get pixel-level ELA, noise pattern analysis, and AI-generation signature checks. Applicants photographing hard-copy bank statements or itineraries on a phone get the same rigour as a digital upload.
Does it work across different countries' document formats?
Yes. The checks analyse forensic properties - font metrics, structural fingerprints, branding plausibility - rather than matching against country-specific templates, so the same pipeline verifies supporting documents regardless of the issuing country or consulate.
How is this used in a visa processing workflow?
Government agencies, immigration consultancies, and corporate mobility teams typically add TamperCheck at the document submission step - each supporting document (bank statement, employment letter, itinerary) is verified via a single API call, with the verdict gating progression to the next review stage.
