How do you know if the interview letter was sent when checking your profile at the USCIS site. I see some people get an error message when they check case status online with receipt # but is it the same if you have a login profile. I ask because i used to be able to click on my profile when i sign on and see that case received and pending etc but now, it wont let me click on the profle link, please help I just wanna know if my letter is sent, i had my FP Sept 13 and still no interview letter. I called the 800# and no update on the automated system. Any answer is appreciated!
