Now I would like for her to become British to avoid possible immigration issues later. It seems I can do this through section 3(2) of MN1. This section has a three year clause, as follows:
The time when I lived in the UK for three years in one go is a long time ago and I don't have many records from then (more than 20 years ago). I am wondering what documents I should provide to prove my stay in the UK. I have work records, but they don't cover a full three year period (even though I was in the UK for three years). I also went to school and University in the UK so I could provide education certificates to cover that period, but I can't prove where I was living in the UK anymore. I can provide an address, but the only proof of me at that address is a council tax registration certificate for some of the period (my brother is registered there for the rest of the period, but not me).The British citizen by descent parent must have lived in the UK (or, if the child was born on or after 21 May 2002, in a British overseas territory) for a continuous period of 3 years at any time before the child’s birth. During that period they should not have absences exceeding 270 days. The application must be made whilst the child is under 18 years of age.
The 3-year residence requirement for the parent does not need to be met if the child is stateless.
Could someone advise on what sort of documents I could provide to prove I lived at an address or how this address will be checked in the UK, given that the UK has no requirement to register at your local council.
(Side note: My older daughter was born in the UK and is British automatically, but I don't think that would influence the application in anyway)
