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
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.
