I am on F1 visa with stem extension valid till feb 2019. My employer sent H1 my application to USCIS this year already. I am planning to travel to India from April 15th to May 2nd. Is it a wise choice to travel during this time? I got to know that at the port of entry, they will check my intent for present visa( F1) and if they see that I requested for a change of status from F1 to H1, they will cancel H1 and they will not let me into the country even on F1. How true is this?
