Having gone through the immigration stuff myself, I'm going to go out on a whim and say that Kirlyam has received her green card. I follow her on instagram, and she very recently posted a video of her and her husband announcing that they are going to Brasil. Marriage to a citizen alone doesn't grant a person the right to live in the states. If she left the country (USA) without having an adjustment of status finalized and approved, she wouldn't be allowed to reenter.
Perhaps she isn't employeed yet because she is still working on perfecting her English - or perhaps she and Alan (I think that's her hub's name) decided she would be a stay-at-home wife (and eventual mom.) I don't get why people would assume he is hiding her green card or work permit just because she isn't working.
