Hello,

Here is the timeline.
Dec 23rd - First update, my application was received.
Feb 20th - Approved and card sent for production
Feb 25th - Online status changed as my card was mailed to me.
Till date no USPS tracking info.

I made two service requests first one for USPS tracking info and the second one for expediting my case since it was 87 days and also I mentioned that I had a job offer which will be revoked if I don't have my card within a week. On March 24th, they sent a response through mail which I am yet to receive. So I called them up and asked for the response that they sent. They mentioned that "we sent out the card on 25th Feb and we have no record of your card being returned back to USCIS. Hence we have concluded that your card has been lost in transit and have to file a new I-765 application". They updated my service request for the USPS tracking info. When I again called them up to ask for the response they said I have to file a new I-765 application. Spoke to USPS but no use since I don't have a tracking number.
