I need some information if anyone has experience or relevant information please share your valuable feedback.
My wife is applying for her naturalisation application along with my two sons both are under 15 years old.
1. Wife
2. Son 1 Age 14.10 Years (Born abroad)
3. Son 2 Age 13 Years (Born abroad)
Our queries are;
1) I am a British citizen (received couple of months ago). She has been in the country since in 2012, my Wife and both Sons has ILR from 2020, Can you please clarify if she and sons are eligible via the 3 years route as partner for BC or 5 years?
2) I believe after my wife application my two sons can be add on the same time?
3) My Wife has cleared the English language requirements (Passed B1 test) when she got ILR in 2020 . I believe That English test B1 is valid for her British naturalisation application? or doe she need to pass again? also Life in the UK should be valid as well?
4) ''Proof of living in the UK for 5 years if applying in your own right or 3 years if applying as the spouse of a British Citizen'' - is the proof her and their current passport?
5) My wife she is house-wife(never worked), she has NI number, For employment what should we state and provide?
6) I read on this form the that for Children under 18, there is a consent form which both parents needs to signed and submit? would my wife also sign that as she will be the main applicant?
7) what supporting documents would be required for my Sons?
