I got a email about my pending 485 form USCIS as below:
On March 16, 2007, the post office returned our last written notice on this case as undeliverable. This can have serious effects on the processing of this case. Please call 1-800-375-5283 to update the mailing address so this notice can be re-sent.
I filled out AR-11 and called USCIS when I moved last year.
I had my first FP in septermber of 2005.
What should I do? How serious is the effect?
Thanks!
