回复：visa application in Beijing

I have the same question. Most people told me that if I
do not have a H1 stamp on my passport (I transfer to H1 from F1 in the States) and I come back with AP, I will lose my H1-B status automatically. Then I will have to go home with my H1-B. How long does it take for a security check? I've waited for more than two years for my I-140, haven't they checked enough?
