Can someone please guide:

I am applying for British Citizenship for my child, age 14. She was born outside UK (India) and have been in the UK for 13 years i.e. initial 6.5 years as PBS dependent and latest 6.5 years having ILR. The parent, I, have British passport since 2017 and my wife has been having ILR since 6.5 years.

Should I choose Other - apply at the discretion of the Home Secretary ?

Yes - Other.

Can I please check if the referee for child UK Citizenship be any British Citizen above 25 years old and knowing the child for 3+ years ? Or the person must be professional person e.g. teacher of the child.

Two referees are required. One a professional and one who is british.
