Trouble with USPS??!!

I was approved. Yay! USCIS reported USPS picked up my EAD on the 13th. It's been stuck on: "Departed Knoxville TN sorting facility". I haven't got any update since. Should I be worried? I'm giving it a few extra days since USPS is horrible. -_- I'm only worried because I've read forums about USPS loosing peoples EAD. Ugh. Help anyone?

that happen to me it said depart usps sort facility mcallen texas november 15, 2013 i finally got my ead card december 17, 2013...i had to call my congressman and tell him my situation and ge helped me

How do you get a tracking number

How do u get a tracking number

USCIS assigned me one, once USPS picked up my EAD. My case as of right now reads:

The USPS reported that they picked up mail from USCIS containing your new card on December 13, 2013. The USPS tracking number assigned is XXXXXXXXXXXXXXXXXXXXXXX. You can use this number at www.usps.com to view updates to the delivery status of your mail. You should receive your new card within 7 days. If you do not, or if you move before you get it, please call our customer service at 1-800-375-5283.

X= 23 digit tracking number
You might want to save the number when you first come across it. I've read forums where, the got a tracking # but it wasn't showing it anymore or, USCIS customer service says they can't provide you with one, etc...

Thank God you received yours & didn't have to reapply for a new one. I've read forums where USPS looses their EAD & the only option is to reapply. :/ Bummer* Luckily I got an update today saying my EAD is in a nearby USPS. It's so frustrating reading people got it in less than 3 days. I hope I get mine before all the Holidays. -_-

All it's say is that my card was mailed

Call uscis and ask for your tracking number

Ok thanks
