I submitted my I485 Application on May of 2005 and I received my work permit at the end of June of 2005. My interview was in September of the same year. The officer said that everything was approved and I should just wait for the clearnce for my security background check and he also said that it was going to take about a week or two. It's been almost 2 years now and I haven't received anything from them, and everytime I call them they send me a letter in the mail asking to call them after 6 months. Any Help would be reaaaally appreciated.
