On September 19th I went for my interview and my IO told me they needed addition information.Within 3 days time I gathered all what my IO told me I needed . Its been two weeks and I am still waiting on this letter called the N-14. Online uscis site says it been sent out on the 19th. I called customer service and they resubmitted a request for the letter.I have also made an info pass to see if I can talk to an IO there explain my situation and see if they will accept the letters requested that day. I have 29 days before my GC expires and I am soon to be laid off from my job due to the industry. No GC no job nor Unemployment .I am lost to what else to do
