I am currently working in industry and will be in H1B status starting October 1st. I am returning to academia for a postdoc and my advisor wants me to start around July 20th. The process has already been dragged out a bit, but is it out of line for me to ask whether the official start date can be moved to early October? We are talking about 2.5 months. I feel like getting an H1B visa is worth a lot and definitely preferable to being in J1 status which would be the case if I start in July. Does it help the university at all if they don't have to get me a J1 visa?
