In immigration law, deception means a deliberate act that makes the Home Office believe something untrue, such as giving false information or a false document, or not disclosing a relevant fact. If the Home Office is satisfied an applicant used deception, the application must be refused and a 10-year re-entry ban follows.
Key points
- Paragraph SUI 9.1 of the Immigration Rules says an application must be refused if the decision maker is satisfied the applicant used deception.
- Home Office guidance defines deception as an act which deliberately causes someone to believe something that is not true.
- A refusal for deception means future applications must be refused for 10 years. A refusal for false representations under SUI 10.1 does not lead to a ban.
- The Home Office must prove deception on the balance of probabilities. Innocent mistakes and minor errors such as typographical errors should not be treated as deception.
- In some in-country cases the applicant must be told of the allegation and given a chance to respond before a decision is made.
How deception works
Under Part Suitability of the Immigration Rules, an application for entry clearance or permission must be refused where the decision maker is satisfied the applicant used deception. The Rules give two ways this can happen: by making false representations or providing false documents or false information in relation to the application, or by not disclosing relevant facts.[1]Home Office, Immigration Rules: Part Suitability
The Rules do not define deception. Home Office guidance says “false” means not true or misleading, and “deception” means an act which deliberately causes someone to believe something that is not true.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance) The guidance says the mandatory refusal requires a deliberate intention to deceive by the applicant.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
A false document includes one that has been altered or tampered with, a counterfeit, a document used by an imposter, a document that was fraudulently obtained or issued or one containing a falsified entry clearance, visa or endorsement.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance) Not disclosing a relevant fact depends on context. The guidance lists a criminal conviction, a previous refusal, previous travel to the UK and family members as examples. It also says a person is not required to volunteer information unless the context makes clear it is needed.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
Deception and false representations
There are two separate grounds. The consequences differ, so the table sets them side by side.
| Deception (SUI 9.1) | False representations (SUI 10.1) | |
|---|---|---|
| Refusal | Must refuse | May refuse |
| Who made the statement | The applicant, or a third party the applicant knew about and was involved with | The applicant or a third party, whether or not the applicant knew |
| Applicant’s knowledge or intent | A deliberate intention to deceive by the applicant | Not needed |
| Re-entry ban | 10 years | None |
| Cancellation of permission already held | SUI 9.2, for permission extended under section 3C, if the applicant used deception in an application to stay | SUI 10.2 |
The sources for the table are the Rules and the guidance.[1]Home Office, Immigration Rules: Part Suitability[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance) Guidance says a refusal under SUI 10.1 or SUI 10.2 does not lead to a ban.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance) See cancellation of leave and section 3C leave.
Proof, mistakes and the chance to respond
The burden of proof is on the applicant to show they meet the requirements of the Rules. If the Home Office alleges deception, the burden is on the Home Office to show both that the representations are not true and that there was deception. The standard of proof is the balance of probabilities.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance) The guidance quotes the Court of Appeal in Balajigari v Home Secretary, which says the seriousness of the allegation and the consequences must be borne in mind.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
A decision maker must consider whether there was an innocent mistake. The guidance says not to refuse for deception where there may have been an innocent mistake, or for minor inaccuracies such as typographical errors. An application can still be refused if the mistake means the route requirements are not met.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
In some cases the applicant must be told of the allegation and be given a chance to respond. The guidance calls this a minded to refuse notification. It applies where the consequences of a finding are significant, for example for someone in the UK seeking further permission or settlement. Normally 14 calendar days is enough time to reply. At the border an explanation is expected in the interview.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
Example
Maria applies to extend her permission. Her form leaves out two earlier refusals of entry clearance. The Home Office writes to her setting out the allegation and asks for her response, normally within 14 calendar days. It then decides whether it is satisfied, on the balance of probabilities, that she deliberately did not disclose a relevant fact.
Piotr types a wrong postcode on his form. The guidance says a decision maker must not refuse for deception for an inaccuracy like this.[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
These examples show how the guidance reads. They do not say how any real case will be decided.
What people get wrong
Many people think any error on a form leads to a ten-year ban. It does not. The ban follows a finding of deception, which needs a deliberate intention to deceive. False information without that finding can lead to a discretionary refusal under SUI 10.1, with no ban.
The second mistake is relying on a third party. SUI 10.1 covers false representations by an applicant or a third party whether or not the applicant knew. If an applicant says an agent made an innocent mistake, the guidance says they should generally provide evidence. That includes a complaint to the agent, any correspondence about it and a witness statement from the agent explaining the error.[1]Home Office, Immigration Rules: Part Suitability[2]UK Visas and Immigration, Part Suitability: Deception, false representations, false documents and non-disclosure of relevant facts (caseworker guidance)
The bottom line
Deception is a deliberate act that gives the Home Office a false picture. A finding means a mandatory refusal and a 10-year ban. False information without deception can still lead to a refusal, but not to a ban. Check which paragraph the refusal letter relies on, because the consequences are very different.
Common questions
The Rules cover false representations, false documents or false information in an application, and not disclosing relevant facts. For a mandatory refusal under SUI 9.1 the Home Office must be satisfied the applicant used deception, which guidance says needs a deliberate intention to deceive.
Not by itself. Guidance says a decision maker must not refuse for deception where there may have been an innocent mistake or where inaccuracies are minor and immaterial, such as a typographical error. The application can still be refused if it does not meet the route requirements.
The Rules set a 10-year period, counted from the date of the refusal. For visit applications it applies to entry clearance applications only. A refusal for false representations under SUI 10.1 does not lead to a ban.
The Home Office can still refuse under SUI 10.1, which applies to a third party's false representations whether or not the applicant knew. It can refuse under SUI 9.1 where it can prove the applicant knew about the deception and was involved in it.
