I brought a fiancée on K1 visa in 2012, but things didn't work out and we broke up right after he had arrived without getting married.
However, he didn't intent to go back to his home country, and I heard later that he had found a way to transfer the visa to a refugee visa and seems to have gotten a Green card after a couple years.
I'm now married to another person from abroad and had 2 kids, and I have recently filed for I-130 petition. Then I've realized that I've signed the Affidavit of Support for the K1 visa for this individual whom I have no contact with any longer. It seems to be that I might still be responsible for this person, but it's uncertain. Would I now need a Affidavit of Support to cover 5 members (4 family member plus this ex)?
How can I cancel the Affidavit of Support for this particular individual who has gotten the K1 visa and reached the US long ago?
I'd appreciate for any help!
