Upgrading from F3 to F1

That sounds like something that people probably do... I wouldn't, but maybe others will.

Well, you need to be unmarried throughout the entire process not just before your priority date becomes available. I don't know what USCIS would think if someone remarries the same person, probably fraud, I would believe, However, I am not certain 

NOw why would that be so? Are you saying that if one files for an F1and gets married it is automatically changed to an F3 or that the F1 becomes void upon marriage?  From what i am reading here one would be an F1 when filed and SHOULD NOTIFY immigrations when they marry which would change them to an F3 with the same priority date but when divorced they go back to F1 with the same priority date.
