If you are a U.S. citizen, once you file Form I130, your spouse is eligible to apply for a nonimmigrant K3 visa. Two petitions are required: Petition for Alien Relative, Form I-130, and Petition for Alien Fiancé(e), Form I-129F.You must file an I-130 form (Petition for Alien Relative) along with two passport-time pictures of the spouse and filled-out Form I-130A for the spouse. The first step is for your spouse to file a Petition for Alien Relative (Form I-130). When filing Form I130, it's extremely important to prepare a complete petition package that includes all of the necessary supporting documents. The team at the Gambacorta Law Office in Phoenix, Arizona can help you apply for and obtain a K3 Visa for your spouse or fiance. The function of this form is to show USCIS that a valid family relationship exists between the petitioner and the individual seeking a green card. Once your spouse arrives in the US, an application for work authorization can be filed. As the petitioner, you'll file Form I-130: Petition for Alien Relative. Submit a payment for your USCIS fees.
