My spouse has purchased a ticket to travel to her home country for end of June, after re-stamping the H-4 in her passport at the consulate she is planning on coming back in August. I am now in condition to apply for I-485 (after doing the medicals and the fingerprinting). I do not know whether is advisable for us to wait until she is back to apply for I-485, or apply in June for Advance Parole along with I-485 and then she departs (she could delay the departure a couple of weeks). I heard that once you apply for Advance parole you cannot leave the country until it is approved; Is this true? Could she take the flight the same day we dispatch the I-485 + AP?, because I know at the time of filing we both need to be present in the U.S., and this way she will be present but just wont have a case recepit number. She is having a valid H-4 and is planning to leave and re-enter based on that only, any suggestions? (as per filing I-485 with our without AP before or after travelling). Thank you so much.
