It generally takes about 7-10 months from start to finish. This includes 5-6 months processing of the I-130 with USCIS, 1-2 months of processing at the NVC and 1-2 for interview completion and entrance to the U.S.
In order to bring your spouse (husband or wife) to live in the United States as a green card holder you must submit Form I-130. Once it is approved, it will be sent for consular processing and the consulate or embassy will provide notification and processing information. It will take 4-6 months. Perhaps longer if more information is needed.
