My Receipt date is FEB 8 2005, my NOA2 was Feb 28th 2005, according to the website of the USCIS when i log in, last update was March 1 2005, i got approved, so when do i get my case number? how do you know the progress of your case? do you get emails from USCIS throughout the whole process or do i need to register at the NVC website? i am confused on how to check for updated information, is USCIS the same as NVC?
