I am British Citizen planing to apply for H1-b visa this coming April 2013, how long will it take to process and to know the result? will it possible to process everything and get visa by October 2013 because planing to move USA by October 2013.
Under regular processing, it can take 2-6 months. If you apply for premium processing, then they will adjudicate it within 15 calendar days. If RFE is issued then it can take longer.
Once approved, you will have to appear for visa stamping. If approved, you are all set. If its put under administrative processing, then it can take few weeks to several months.
