Was Interviewed on 27th April at chatsworth CA office. I had booked tickets for India travel on May 5th hence waiting for the approval results as i did not get stamped on my passport for I155 . But The officer was very polite and very nice to us . One issue was Though my address was updated online and i was getting all my mails on my updated address their files showed no updated address , why can't USCIS digitalize all its document works so its easy for them .
