When You Might Need an Immigration Solicitor

Alternative Route: UK Ancestry Visa

An alternate avenue to British citizenship is the UK Ancestry visa. To qualify for this visa, you need a grandparent who was born:


  • In the UK, the Channel Islands, or the Isle of Man.
  • Before 31st March 1922 in Ireland.
  • On a UK-registered ship or aircraft owned by the British government.

The Home Office guidance permits Ancestry visa application even if you or your parent were adopted or if your parents or grandparents weren’t married. However, step-parents cannot facilitate this application.

With an Ancestry visa, you can reside in the UK for 5 years, and then choose to extend your visa or apply for settlement (ILR). After holding ILR for a year, you become eligible to apply for UK citizenship.
