I thought we were taslking about travelling after OPT expires and H1-B starts( Oct 1st). If we cannot maintain status between that period, we have to leave country. My idea was if H1 is already applied we cannot apply for I-20. It all goes through DHS(USCIS). I heard that the application for I-20 voids any other application on the past... Its not a legal advice....Its all i heard...Thanks guys
