POE experience after succesful CP @ Islamabad
The Immigrant Visa looks like a H1B1 visa stamp but the information is obviously different. The embassy also hands out a packet with top right part perforated. It has a white paper on the front which has your picture and information on it.
I landed at Chicago O'Hare airport at about 3:15 PM. While in the plane, I had filled only the customs forms and not the I-94 white form. After landing, I went to the New Immigrant line. The officer looked at the IV and took the packet from me. He sent me to the NSEERS special registration line.
For immigration need, so far I have got prompt help whenever I ask for. Thank you very much Heather, Mark and Attorney Rajiv.
