Short answer: in visa and immigration applications, an altered or invented document can lead to refusal and, in the UK, a 10-year ban if deception is found, and AI tools can now produce convincing fake bank statements and letters. If you use an agent, you are still responsible for what is submitted. Download your own documents from the source, never edit them, and keep an untouched copy with a dated record.

Why this is in the news
Visa and immigration decision-makers are alert to false documents, and generative tools make convincing fake statements and letters easier to produce. We cannot verify individual stories circulating online, so this page sticks to what official guidance says.
What the UK guidance says
The UK Immigration Rules (Part Suitability) define a “false document” to include a document that has been altered or tampered with, a counterfeit, or one fraudulently obtained or issued. Two grounds matter:
- Deception (mandatory refusal). If the decision-maker is satisfied, on the balance of probabilities, that the applicant deliberately used false documents or information, the application must be refused and a 10-year mandatory refusal period follows, starting from the refusal decision. Home Office guidance says an allegation of deception must not be made without evidence, and that incorrect information without proof of deliberate deception is treated differently.
- False representations (discretionary refusal). An application may be refused where the applicant or a third party provided false documents or information, whether or not to the applicant’s knowledge. That is the point for anyone using an agent or consultant.
Other countries have their own rules and penalties. Read the official guidance for the country you apply to and, for anything important, take advice from a regulated immigration adviser or lawyer.
What applicants should do
- Get documents yourself, from the source. Download bank statements, payslips and letters directly from the bank or employer portal, or request an official copy.
- Never alter anything. Do not fix a date, add a balance, or “tidy” a PDF. Do not let an agent do it either. If a figure looks wrong, ask the issuer for a corrected document.
- Check what your agent submits. Ask for the exact files and the submission receipt. Compare them with your originals.
- Keep originals untouched. Store the files as downloaded, with the email or portal message that delivered them.
- Keep a dated record. Make a SHA-256 fingerprint in your browser with our hash checker, and a TimeBind of the originals. If a decision-maker later questions a document, you can show the file you hold is byte-for-byte the one you downloaded then. See how to prove a file existed before a date.
- Respond to concerns quickly and in writing. If an officer says a document is suspect, offer to have it verified with the issuer and keep a copy of your reply.
What a dated record can and cannot do
A TimeBind shows that an exact file existed no later than a recorded time and still matches. It can help show that a document was not changed after you downloaded it. It does not show that the document is genuine, that the bank issued it, or that an application will succeed, and it cannot repair a document that was false from the start. Decision-makers will rely on verification with the issuer, not on our record.

This is general information, not immigration advice. Rules, burdens of proof and penalties vary by country and change. We are not a regulated adviser. If an application has already been refused for alleged deception, speak to a qualified adviser at once.

Frequently Asked Questions
-
What happens in the UK if a false document is used in a visa application?
If the Home Office is satisfied the applicant deliberately used deception, refusal is mandatory and a 10-year mandatory refusal period applies from the date of the refusal decision. Where deception is not proved, a refusal can still be discretionary if false documents were supplied, including by a third party, whether or not the applicant knew.
-
Am I responsible if my agent submits a fake bank statement?
UK guidance allows a discretionary refusal where a third party provided false documents, whether or not to the applicant’s knowledge. Always check exactly what your agent submits. Other countries have their own rules.
-
Can I tidy or crop a bank statement before applying?
Do not alter the document. Ask the bank for a corrected or official copy if something is wrong, and keep the original untouched.
-
Can a blockchain timestamp prove my documents are genuine?
No. A TimeBind shows an exact file existed no later than a recorded time and still matches. It does not show that the bank issued it or that the contents are true.
-
What if an officer says my genuine document looks fake?
Offer to have it verified with the issuer, provide the original file you downloaded, and respond in writing. For anything serious, take advice from a regulated immigration adviser or lawyer.
