My case is brother sister petition I-I30 and my priority date is 26 March ,2007. When my visa number will be available? How much time it will take? USCIS have approved my case and sent the same to NATIONAL VISA CENTRE. Now what should we do. Can we wind up our businesses and services here in Pakistan or there is a waiting in line for severle years? Please answer correct and earley. Thanks MUHAMMAD TARIQ KHAN SIALKOT PAKISTAN. TARIQ KHAN
