Can i apply for a british passport if my grandfather was born in the uk, then my father applys for a passport?
British citizenship can only be passed down one generation outside the UK. Your father is British by descent which means he could only pass on his citizenship to you if you were born in the UK. There is one way you could become a British citizen because you have a British grandparent born in the UK (or Ireland before 31 March 1922). If you are a Commonwealth citizen over 18, you may be eligible for an ancestry visa. This is a five year visa that allows you to live and work in the UK without having to meet the stringent work visa criteria. After working in the UK for five years, you can apply for indefinite leave to remain (settlement). After a year holding ILR you could be eligible for citizenship.
