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 arising from marriage to a British citizen.

Partners of British citizens are eligible for a UK spouse visa 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)

Evolving citizenship laws enshrined rights to women who were married to British men before 1983 and to also to the descendants of women married to a British man before 1949.

We can assess your eligibility to become a UK citizen by naturalisation:

Marriage to British Man before 1983

Women who married a UK citizen (or a man that could qualify for UK citizenship by descent) before 1983 will often today be British citizens, or entitled to live in the UK.

The caveat is that the women must have been a Commonwealth citizen (by birth or descent) on 1st January 1983.

Importantly, previous marriages can also convey rights.

Marriage to British Man before 1949

A woman who married a British man (or a man that could qualify for UK citizenship by descent) before 1949 acquired British Nationality upon marriage, and could be British citizens today.

Importantly, previous marriages can also convey rights.

Any children born to this woman can claim British citizenship.

Due to complex British citizenship law, there is the possibility that if you were married to a British man you could claim British nationality, alongside a further generation.

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 Once the information has been supplied, it cannot easily be changed or withdrawn. If your application is refused, the application fee will not be refunded.
