A: The approval of the FORM I-130 will be transferred to the National Visa Center (NVC) by USCIS if you have requested on page 8 ( #62 a-c) of the petition that you are requesting consulate processing of the case.
The NVC will then contact you to request filing fees. You can access the CEAC.state.gov website to obtain the list of documents needed to complete the processing of the case with the NVC agency.
Good luck to you.
A: Apparently, you are intending to process the case with the NVC and the U.S. consulate by filing the DS-260. The approval of the relative petition (FORM I-130) can be “cancelled” by the National Visa Center (NVC) if you fail to maintain contact with that agency and you allow a year to lapse.
