It has been so long since I have seen a K3, from memory a K3 is good for 2 years rather than 90 days. So you would need to marry, then file for K3 then move then file to adjust and obtain adjustment all within 2 years to need to remove conditions, all of which seems unlikely, on top of actually getting a K3 in the first place.
If it is something else well then all bets are off.
