Hey guys,
Just a small update.... Yesterday I called my CO AH about the status of my application.He replied that the department is waiting for the internal security check, at this point there is nothing to do but to wait, and the waiting period may take up to several months. Now I have already waited for more than 7 months (applied in August '13). Submitted all the requested documents by CO for more than 2 months ago. This is really funny. Though I know there are some people who are waiting long before me but it's depressing when most of the people are getting their visa within 3/4 months. Life is definitely not fair. Anyway, best of luck to everyone.
