So, I'm sorry this happened, and it's one of the reasons I naturalized - as much as things are bad now, I have my life here, and, if I ever lived abroad again (like we're looking at now) I didn't want to be in a quagmire should migratory laws change and I needed to return.
I gotta ask OP, why didn't you just get a DNI? You don't even have to be married, being partners is sufficient. Now it's going to be a PIA to do all the legal stuff to get back here (plus expensive) while putting your guys' lives on hold.
Caveat emptor to all the folks who still think it's kosher to live in gris here, either come as a tourist or get residency, there's no 3rd option.
