Hello Ron and thread members My wife entered USA on H4 Visa in 2011 and we traveled back to India in 2013 and she got her H4 visa stamped (ending now in Dec 2015). Last year in August she got her i_539 approved for COS to F1 ( which expires August 2016) since she was pursuing a medical course (No degree or anything just private courses) and she has her approved 797 and I-20. We want to get her F1 converted to H4 to take advantage of the EAD rule (since I have my I-140 approved). I think there are two ways to get it : 1. I can file for COS in USA ( USCIS is taking 6 months to get it done) 2. Traveling Abroad = We are thinking of traveling to Canada for 10 days in early May (can she leverage her valid H4 stamp) to get an entry in USA from Canada, if yes then her F1 status will be revoked and she will be on H4 thereafter ? Thanks a lot for all your support and guidance over this matter.
