Need some serious help! If this is not the right forum plz excuse me. I tried to look for this answer, but I was not able to find it. I am a Canadian Citizen who recently got married to a Green Card holder. I would like to sponsor her to come live with me in Canada. 1) Will she have to give up her green card? 2) Can she be a citizen of both the USA and Canada and if yes does it matter as to which citizenship she gets first?
