Nov2007 - this is your year my friend. Relax. You will get your GC by Sep 2013. If you don't - that definitely will mean something seriously wrong with your case and you should seek help from a lawyer - call USCIS and all of that. But don't stress out. Take it easy. There is a movie called "Scent of a Woman" where Al Pacino has a great line - "When in doubt ... eff it". Excuse the language but the message of the character in the movie (a retired disabled Army/Marine Officer) is to live in the moment and not worry too much.
