My wife and I left Ukraine and traveled to USA to activate her green card. We booked round trip from Ukraine. When we check in at Detroilet, Mi to travel back, I was jammed for not having any idea when I was returning to the US. I was told I had to book a return ticket not more than 90 days because of new policy changes. Then I pulled out the good ole Ukrainian TRP. That document gathered quite a few people scratching heads, and after a long debate they issued a boarding pass.
I asked where could I find this new policy to read for myself....did not get an answer
