The National Visa Center sent our paperwork to the Embassy on 4/20/2011, still waiting for them to send out packet 3. What is the priority date? I dont understand it. My priority date is 10/1/2011, what does this mean? Please help. I'm hoping my fiancee has her interview in June or July at the latest. Our baby is due around October 10th. Also if anyone has gone through the embassy in Ho Chi Minh city please share your experience, thanks.
