Vera and I have just returned from the Immigration interview in Baltimore. It was for about 30 minutes total, they did not ask to see any documents or pictures nor did they want a copy of everything I had made for them even when I offered. They said she would probably get her green card within 4 weeks or less and that it would be good for about 2 plus years. The interview was conducted with video and audio for the record, so we were well aware of that and all seemed to go very well.
We both thank you so much for your advice and walking us through each of these steps. All is well with us and I wish we had met years ago instead of having to experience other disasters first.
