Under the International Marriage Broker Regulation Act (IMBRA), the petitioner of a K-1 fiance visa petition or K-3 petition for an alien spouse must submit information on any criminal conviction for specified crimes with the Form I-129 nonimmigrant visa petition. Also, IMBRA imposes time and numerical filing limitations, establishes a waiver of these limitations (including a general waiver, an extraordinary circumstances waiver in cases involving a history of violent offenses, and a mandatory waiver in cases where the petitioner was subjected to battery or extreme cruelty), and requires the US Citizenship and Immigration Services (USCIS) to track repeated petitions. Please see the USCIS website.
