I was a student on F-1 (MS), and I got my H-1B two years ago. My company has started GC process and already got my I-140 approved. But I want to go back to school this fall (law school), which means I'll have to change my status back to F-1 again.
Video Transcript: If you have exhibited immigrant intent, getting F-1 status should be very difficult. So it is correct that when you have exhibited an immigrant intent the government or the counsellor officers can take the position that you have basically taken yourself out of consideration for a non immigrant visa like a student visa.
Theoretically at least your chances are made worse because of the green card. I don't think withdrawal of the I-140 necessary helps.
