I have a stamped H1B visa which expires on Nov 2, 2016. I intend to travel to India during the last week of September and intend on return to US in the last week of October. 1. Will there be a problem if I re-enter US with 1 week remaining on my stamped visa? 2. I intend to get my H1B extension done by PP in June, so when I travel to India I will have my new approved I-797 with extended expiry date. However, I have no intentions of getting my new visa stamped and hence, the re-entry before the last one expires. Will there by any problems at POE? Will I get I-94 based on new date or the old one as I will use that to re-enter? Anyone have a previous experience like this? Thanks in advance.
