I’m currently on an H1b visa and travelled to my home country for visa renewal. I was given a blue 221g (administrative processing) and was not asked for additional evidence. They kept my new passport and new i797. I have my old passport with my still current h1b stamp that expires in June. I also have my old i797. I’m wondering if I can reenter the US with my old h1b stamp and old i797 while awaiting administrative processing for the renewal? I would need to collect my new passport from the embassy but don’t know what possible repercussions I could face if I do that and if they would let me reenter the US.
