Please I need your kind advice on the following issue.
I am a citicizen from another country, I am just qualified to apply for British Naturalisation now having spent more than 10 years in the UK (and I have got UK ILR for more than 12 months). I also have pending settlement visa application with USA (through USA citizen brother that filed a settlement petition/application/sponsorship for me).
(a) Is it legal to have three passports (i.e (1) birth citizenship, (2) UK by naturalisation and (3) later, USA by naturalisation via green card/settlement visa)?
(b) If I submit my UK naturalisation application now and get UK passport before obtaining USA settlement visa/green card, will I be able to still legally obtain USA passport in future?
Thanks in advance.
