UK Ancestry – a potential route to British citizenship?
If you have a British grandparent and you are a Commonwealth citizen, then if you are not British but you may be able to come to the UK under the UK Ancestry visa route providing that you are a Commonwealth citizen, 17 years of age or over and have a grandparent who was born in the United Kingdom and you intend to work or be self-employed in the UK and able to maintain and accommodate yourself. That is a route that leads to settlement and eventually naturalisation as a British citizen.
