Brit birthright?

I was just wondering. Tonight my mom calls me and tells me she found my grandfathers birth certificate. It clearly states his father lived in Liverpool UK. Does this give my mom or anyone in my immediate family a Brit birthright?  I  mean could my mother for example actually move here and obtain some sort of residency visa?

So your mother's grandfather was British, am I reading that correctly? If that's the case, sorry no nobody gets anything. Some Commonwealth countries can get a 4 year "grandparent visa" through their Brit grandparents but I don't think there is anything like that for non Commonwealth citizens, or citizenship by descent via a grandparent

I think it's her mothers father.

hmmmm....well my great grandfather immigrated here from Poland. My grandfather was born here.

To my understanding, she can get an Ancestry Visa, but she has to provide proof that she intends to work.  It is valid for 4 years but can be extended. 

I'm confused. Who was from Liverpool?

Sorry, I read it as my grandfather, assumed it was Pebbles mom

My moms father was born here (Liverpool)

Isn't that only for Commonwealth citizens?

Actually, you might be right.  But I am not sure because when I was speaking with recruitment agencies, I would tell them I was American and they would ask me if I was eligible for the Ancestry Visa. 

Just checked, it is Commonwealth countries: http://www.ukvisas.gov.uk/servlet/Front?pagename=OpenMarket/Xcelerate/ShowPage&c=Page&cid=1018721067684#Q1

The recruitment agencies are probably used to dealing with a lot of Aussies, Kiwis etc who have ancestry visas.   

Thanks everyone. I was just curious   

These things are always worth a try. A friend of mine got an EU passport because his grandfather was Irish.

This is only for Commonwealth nationals.  If, however, you have an Irish grandparent (including those born in N. Ireland), you can claim Irish citizenship and therefore be an EU national.
