If the K1 visa expired

If you are in the situation that your US k1 visa or fiancée visa has expired and you’re not able to adjust your adjustment of status yet after marriage, you still eligible or have a chance to apply your Status (AOS) still, it has no penalty at all but however, you should avoid travelling to other places or states within United States when your visa has expired because you will be checked at any border patrol checkpoint and if you’re caught you will be considered as illegal overstaying out of status since you did not file your “AOS” or adjustment of status yet before the visa expiration. Obviously, it usually happens due to the financial problem. I can relay with it.
