Once the I-130 petition is approved, the case is transferred to the National Visa Center (NVC) for consular processing if the beneficiary is outside the United States. The NVC assigns a case number and requests payment of immigrant visa and affidavit of support fees. The petitioner must submit Form I-864 along with supporting financial documentation, and the beneficiary must complete the DS-260 immigrant visa application. After document review, the case is scheduled for an interview at the appropriate U.S. consulate.
