What is the average receipt notice time you have seen here? Have you sent anything to the USCIS lately? Even on Reddit not many who are posting got receipt notices in the stipulated 30 day time frame.
Last year, my EAD expired in September. I sent my renewal packet in February, got a notice(after Congress person intervention) it was sent to Nebraska in June! Then got another notice it was returned to Vermont. No receipt notice from VSC till August. August, I got HRs notice requesting my renewed docs. I called and expidited-NOTHING! Thankfully, HR was kind to me and found a way to extend my authorization without the documents.
It was 2 weeks after my EAD expired that USCIS responded to my expedite request and issued my 5 yr EAD. NOONE cared if I lost my means of livelihood or suffered trauma from the uncertainty of the whole process. I will advice even my enemy to send early. But hey, I'm not an expert, just speaking from a recent traumatic experience.
