Are you the RSO filing for a fiance visa?
I read about the case of a Woman and her child (both from the Philippines) who were able to get a fiance (and K-2 for the child) visa but whose application for permanent residency (AOS) got denied because the U.S. Citizen husband was an RSO. This was a Board of Immigration Appeals case.
Unless the Adam Walsh Act gets repealed or declared unconstitutional by the U.S. Supreme Court, I'm afraid you face an uphill battle.
If subject to the Adam Walsh Act then the bar is extremely high to get a petition approved.
I've seen many couples in that situation choose to move to a foreign country rather than continue the near-futile attempts to bring the alien here.
