naturalised english and english are two different things though. as i said before, you cant just change your nationality. you cant be x for 30 years then y for the rest. it doesnt work like that, however the difference is, your children can change. by that i mean, if you move to a country, while you will never take that nationality fully because you will always be your original nationality, your children if born there or move at a very young age will always consider themselves that countries nationality because they grew up there, spoke that language went to school there etc etc.
