Yes, your Thai wife’s brother can apply to visit you in the UK. For a temporary family visit, he would normally apply for a UK Standard Visitor visa. His relationship to your wife does not give him an automatic right to enter the UK, but you can invite him, offer him a place to stay and help pay for his trip.
What does he need to show?
He needs to show that he is coming for a genuine, temporary visit and intends to leave the UK afterwards. The application should explain why he wants to visit, how long he plans to stay, how the trip will be funded and what his circumstances are in Thailand.
Evidence of work, a business, studies, family responsibilities or other commitments may help explain why he will return. There is no single document that guarantees a visa. The evidence needs to tell a clear and consistent story about his situation.
Can we sponsor my wife’s brother?
Yes. You can provide accommodation, pay for his flights or contribute to his living costs. Your invitation letter should explain your relationship, the purpose and dates of the visit, where he will stay and exactly what support you will provide.
Include suitable evidence of your UK address and finances if you are providing accommodation or paying for the trip. It may also help to show how he is related to your wife. Your support can cover the cost of the visit, but he must still satisfy the visitor requirements in his own right.
What documents might help?
- His valid Thai passport and details of the proposed visit.
- Evidence of his employment, business, studies or other commitments in Thailand, where applicable.
- Bank statements and an explanation of how the trip will be paid for.
- Your invitation letter and evidence of any accommodation or financial support you will provide.
- Evidence of the family relationship, where useful.
- Translations of relevant Thai documents that are not in English or Welsh.
The proposed trip should be realistic for his circumstances. For example, if he works full time, explain how much leave he has been granted and why the planned visit fits within it.
What if he has been refused before?
Read the refusal letter carefully before submitting another application. A previous refusal does not automatically prevent him from applying again, but a new application should address the reasons given and include any missing or clearer evidence. Our guide to a refused UK visitor visa explains why reviewing the refusal first matters.
