When applying for a UK dependent visa, the consistency of the information provided is crucial. While it’s not mandatory for your spouse to change her last name on her passport, it’s essential to ensure that the names on both your passports and supporting documents match to avoid any potential issues with your visa application.
In your case, where you have mentioned your spouse’s name with your surname in your passport, it’s advisable to provide supporting documentation that explains this situation. You can include a cover letter or an affidavit explaining the naming convention and the reason for it, such as cultural or personal preferences.
Additionally, you should provide proof of your legal relationship, such as a marriage certificate, to demonstrate the authenticity of your marriage.
It’s crucial to follow the guidelines and requirements provided by the UK Home Office for dependent visa applications and ensure that all documents are accurate and consistent to improve your chances of a successful application. If you have any doubts or concerns, consider seeking advice from the nearest UK Visa Application Centre or consulate for clarification.
