But if he travels on his oz passport, will they say he can only stay for 6 months, we are returning forever, and funds are so very tight if we really don't need to get a new British passport would rather put the money towards flights etc. Or as he along with all of us was born in the UK, and our passports still have a couple of yrs on them,is he automatically given British citizenship ? sorry but I have so much going on in my head right now
