It depends on the current processing time at the U.S. Consulate in Pakistan, but generally, you would start the process in the U.S. by filing for him as the spouse of a U.S. Citizen. Once aproved, the petition is then transferred to the National Visa Center which will process his visa application. Start to finish it could take upto one year (provided he is able to get security clearance easily) before he can come to the U.S.
