I was recently discussing with my American cousins about whether President Trump could end birthright citizenship. I was wondering if he indeed does so, what would the new "US nationality law" be, particularly regarding acquisition of citizenship?
I am not asking whether he will do that or not, I am asking about the likely nature of the new nationality rules regarding acquisition of citizenship. Similar to other Anglophone countries probably?
My question is precisely: What other systems other than bithright citizenship have been proposed to replace acquisition of citizenship in the USA?
