My [Chinese] wife was granted an IR1 visa to immigrate into the USA. As is typical, she has about a 6 month window to enter, this is fine.
How long would she need to stay minimum on this first entry? They say the actual green card would be mailed within 45 days, however I do not want her to have to sit in the USA for 45 days, we've already registered my daughter in school in Shanghai.
Can we enter, and turn around and leave without any issues even though the physical green card has not been received? Is there any official documentation about this? I've searched, and I see forum posts (and have not yet found actual documentation from gov sites about this) that go both ways, I just want to know the actual legal situation on it today, in 2016.
Back story: I'm a USA citizen, born and bred, but living in Shanghai. Years ago, my wife overstayed her visa by a couple weeks, inadvertently (because our daughter was in school in the USA, and is definitely a USA citizen) and was refused every single visa since even though it was stamped "cancelled without prejudice", the persons refusing her told her the only way is to get a "green card" and so here we are.
We started this process in 2014.
