Immigration Document Verification
Verify that visa documents haven’t been structurally modified before submission. One fraudulent filing — an edited bank statement, a forged recommendation letter, an altered Certificate of Sponsorship — can trigger a compliance audit or revoke your sponsor licence. HTPBE detects modifications invisible to the naked eye.
Why visual review misses tampered immigration documents
Immigration consultants and global mobility teams process hundreds of supporting documents per month — bank statements, recommendation letters, employment contracts, Certificates of Sponsorship. A single fraudulent document in a visa application can trigger a sponsor licence audit, suspension, or revocation.
Visual inspection catches obvious forgeries: wrong fonts, misaligned logos, spelling errors. But modern PDF editing tools produce documents that are visually indistinguishable from originals. The modifications exist only in the file’s binary structure — metadata fields, cross-reference tables, incremental update chains.
HTPBE analyses the PDF’s internal structure to detect whether a document was modified after its original creation — regardless of how convincing it looks on screen. No baseline copy required, no original document needed for comparison.
Compliance risks from fraudulent filings
- Sponsor licence revocation risk from fraudulent filings
- Altered bank statements meeting visa financial requirements
- Post-signature edits invisible to visual review
- Recommendation letters forged after original signing
What the API detects in immigration documents
Forensic analysis across three common document types
Certificates of Sponsorship
Altered sponsorship certificates are among the most common forged immigration documents. HTPBE detects metadata inconsistencies and structural edits in seconds.
Bank Statements for Visa Applications
Applicants sometimes submit edited bank statements to meet financial requirements. Our forensic analysis catches Excel-modified PDFs and balance alterations.
Recommendation & Support Letters
Post-signature edits to recommendation letters leave structural traces detectable by HTPBE — even when the visual presentation appears unchanged.

Step 1 — POST /v1/analyze

}The API returns a structured verdict with named markers. Modified means the PDF was structurally altered after creation. Intact means no modification traces found. Inconclusive means the file lacks enough metadata to determine either way.

Frequently Asked Questions
Can HTPBE detect tampering in a Certificate of Sponsorship PDF?
Yes. HTPBE analyses the PDF’s internal structure — xref tables, metadata fields, incremental update chains, and digital signature integrity — to detect whether the document was modified after its original creation. This works on Certificates of Sponsorship, recommendation letters, bank statements, and any other PDF document.
Do I need the original document to verify authenticity?
No. HTPBE performs one-sided forensic analysis on the single submitted file. No baseline copy or original is required. The analysis uses internal structural signals present in every PDF.
What document types does HTPBE support?
HTPBE analyses any PDF document: bank statements, recommendation letters, Certificates of Sponsorship, transcripts, employment letters, and other supporting documents commonly used in visa applications.
What does HTPBE return if tampering is detected?
HTPBE returns a structured verdict (Modified, Intact, or Inconclusive) with named markers explaining exactly what triggered the verdict — for example, “Modification date differs from creation date by 3 days” or “Incremental update detected after digital signature.”
