Posting for my husband, who attended his interview on March 17th, 2015. His appointment was for 8:00am, he arrived at 7:20am. The overall process was very simple, however they had misplaced his medical papers which added an extra hour. He was out of the building by 11:30am with an approval!! (They hardly asked him any questions at all about our marriage, they just wanted all the correct paperwork)
