No,not my ex husband.
I came on k1 visa to marry a deferent guy but things did not work out so I ended up overstaying as you may know if you don’t get married in the 90 days that you have, you have no other option but to leave the country.
I meet my ex husband after that and we got married and he is the petitioner.
That is why I left the country and attend the interview in my country when I got my waiver of 601a approved here at the USA.
and since we were married more than 2 years I got a permanent resident.
hopefully I did explain every thing.
