Detect tampered and deepfake Employer Leave Approval

What a genuine employer leave approval letter contains

A leave approval letter for a visa application is addressed to the embassy or consulate by name, on the employer's letterhead, with the registered address and a date of issue. It gives the employee's name exactly as the passport spells it, the passport number, the designation, the date of joining and often the salary, then the approved leave dates and the day the employee is due back at work. It closes with a statement that employment continues, the signatory's name, title, direct phone and email, and a company stamp.

Those dates are read against the rest of the application. Approved leave has to cover the whole itinerary in the flight and hotel bookings, and the return-to-work date has to fall after the inbound flight rather than before it. Name spelling and passport number must match the passport page character for character, and the salary and tenure stated here have to agree with the payslips and bank statements filed alongside. The contact details matter because a consulate may use them.

How employer leave approval letter forgeries are made

• Leave dates stretched

  The approved period is widened past what the employer signed off, so the letter covers a longer trip than the applicant actually has leave for. It is the edit with the clearest motive on this document, and it usually puts the leave window out of step with the return-to-work date printed a line below.

• A letter recycled for a new trip

  Last year's approval is reused with fresh dates typed over the old ones, sometimes leaving a date of issue months older than the application it supports. The retyped dates carry a different rendering profile, and the original creases and scan artefacts run underneath text added long afterwards.

• Applicant details replaced

  The name and passport number are swapped so one employer's genuine letter serves a different applicant. A passport number is a dense string in a fixed field, and a substituted one rarely reproduces the character spacing of the value it displaced.

• Salary and designation inflated

  Stated pay is raised to support the financial requirement, or the job title lifted so the employment looks harder to walk away from. The figure then contradicts the payslips and account statements filed in the same application, which is where a consulate compares first.

• An employer that is not one

  The applicant is self-employed, between jobs or working informally, and a company is invented or borrowed to supply the letter. Nothing has been edited, so the assessment rests on how the letterhead was produced, whether a direct contact line is plausible, and whether the same branding recurs across other documents in the pack.

• Stamp and signature placed digitally

  A native PDF carrying a crisp stamp and a vector-smooth signature was never on paper. Consulates that require a wet stamp treat that as material rather than cosmetic, and a flat overlay is separable from an impression that picked up the texture of the sheet beneath it.

What TamperCheck checks on an employer leave approval letter

TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class.

• Stamp authenticity and placement

  Stamps are assessed for whether the ink was impressed onto the page or printed as part of it, and for whether the impression was placed digitally after the fact.

• Letterhead, logo, and issuer plausibility

  Issuer branding is checked for resolution and compression consistency against the body text it sits on. A logo lifted from a website carries the signature of its source, not of the document.

• Date and validity consistency

  Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension.

• And many more checks

  The three above are the layers that carry the most weight on an employer leave approval letter. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks.

Who verifies an employer leave approval letter, and why

Consulates and visa centres confirming employment ties for Schengen applications. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging.

How to verify an employer leave approval letter in 4 steps

1. 1

   Check the fields against each other

   Read leave dates, return-to-work date, and HR signatory together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original.

2. 2

   Inspect the file metadata

   Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look.

3. 3

   Ask for a second document

   Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare.

4. 4

   Run a forensic check

   Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on an employer leave approval letter and returns a risk score from 0 to 100 in about a minute, at $0.50 per document.
