I am a British citizen who just returned to the U.K. after my OPT expired. A U.S. employer is filing an H1-B for me on April 1st (2016).
Am I allowed to reenter the U.S. on an ESTA before and during this process? If I come into the U.S. on an ESTA in the last week of March for a vacation, do I have to make sure I’m out before April 1st (when the H1-B application is filed), or could I leave on April 10th or so?
Similarly, I would like to come back for a week on so in the summer. Can I come in (again, on an ESTA) and leave even though my H1-B doesn’t kick in until October 1st?
Many thanks in advance for your help!
