How long does it take usually for I-130 to get to the NVC stage?

Each of the service centers of USCIS have their own processing times. The estimated range from the Texas service center means that it may take up to 10 months for the I-130 to be processed. After approval, I-130 petitions are expeditiously sent to the National Visa Center within days. After receipt by the NVC, you and your wife would send the NVC documents and when the documentation process is complete, the NVC will work with the US embassy or consulate to schedule an interview for your wife in Nigeria. On visiting during this period of time, your wife should ensure that she tells the truth about the pending petition and does not commit fraud or misrepresentation in either obtaining a visa (if needed) or speaking with a US immigration officer at the port of entry.
