I have a multiple entry B1/B2 visa and would like to change status to F1. My authorized stay on i-94 ends on 6/10/2012. If I apply for change of status and do not get a reply by my status expiration date, will I be out of status? If my change of status is denied, does that void my multiple entry B1/B2? If change of status is denied, how long do I have before I am out of status? If I leave the US after applying for change of status, but before receiving decision and before my status expires, will be able to use my B1/B2 visa to enter again?
