My I-140 NIW has been approved on 04-07-06 at TSC and Im still waiting for my I-485 approval. I'm currently on H1B visa however I also have AP. I am planing to travel to Canada in August to attend a conference. I plan to use my AP when returning to the USA and not the H1B. Thus, my H1B will be expired after returning to the country. I really appreciate your advice regarding the documents that I need to take with myself when traveling. Do I only need to take my AP? Am I going to lose my I-94 form in the passport as I'm going to be a parole? Do I also need to get a letter from my current employer regarding my job? Is this a straight forward process when returning to the United States? Do I also need to check with immigration office at the airport when Im leaving the country? Any detailed information is highly appreciated.
Thanks
Thanks
