Our nationality lawyers help people with complex claims for British nationality.

Spouses of British citizens

A person who is married to a British citizen and has resided in the UK for at least 3 years may apply to become a British citizen by naturalisation. (Normally a person must live in the UK for 5 years.)

There are no other nationality concessions to the spouse of a British citizen.

Partners of British citizens are eligible for special visas and residence permits under UK and European Union law:

  • Eligibility for a UK settlement visa on the basis of marriage
  • Eligibility to obtain a residence permit for a country in the EEA (other than the UK)
  • Eligibility to get a 2 year Schengen visa for travel in most countries in the European Union (excludes UK and Ireland)

How the British Home Office Works

The correct application forms, correct supporting documents and fee must be submitted together to the Home Office. Application decisions are normally based on the documents originally supplied with the application, so preparation and presentation of information and arguments are crucial to success. Once information has been supplied, it cannot easily be changed or withdrawn. If your application is refused, the application fee  will not be refunded.

About Passportia

Passportia did a first-class job in getting British citizenship for my 2 adopted children in Sri Lanka. Their excellent preparation and credibility with the Home Office made all the difference. I can't recommend them highly enough. Thank you Passportia.
