Juliloew, it would appear from your profile that you are domicile in the UK at present and would have a right-of-abode stamped in your passport based on your mothers birth in the UK her being a UK citizen?
If that is so, then under the proposed changes to section 4c this would be one way to gain citizenship or the right to a Brit passport (by descent). If you already have the right of abode to live in the UK & have been there for 3-years, I believe that you can apply for full naturalization as a UK citizenship (unqualified response)
You are right, I am here in the UK, but not through anything to do with my mother, visa-wise anyway. The way the law stands now, I'm not entitled to right of abode or anything rights to live in the UK through my mother.
But, I wanted to live in the UK since I was a teen! Not having the 'net back in those days, I wasn't sure how to go about it. Really wanted to attend uni here, but didn't get much encouragement from family on either side of the pond.
Fast forward 30 years, one failed marriage, two grown kids later and it seemed like an ideal time to blow a lot of hard-earned money to move to the UK on a student visa to attend uni, which I did. I'm now married to a British citizen and eligible to apply for ILR in May of '09, although I'm really hoping these changes go through before then so I can jump to registration and claim citizenship through my mom. A minor sticking point for many, I'm sure, but I'd like to gain that passport through birth to a British citizen, not marriage to one.
Sorry, didn't mean to give you most of my life's story...
However, I am truly happy to be living in the UK, in spite of missing my kids. Another trip back to see them schedule in just a few weeks!
