EAD (WorkPermit)

We're currently in the process of re-newing our J-2 EAD again. (I know there's usually a couple of other J-2s in the same boat around this time, though I think we lost on of the regulards, JMG-J2-Canadian). Last year was unexpected smooth sailing and we received the new card in under 2 months. This year, we submitted the I-765 package a couple weeks later we would've liked due to unforeseen circumstances. However, even 2 weeks later then when the mail was received at the Phoenix lockbox (tracking receipt), we still have not received a Notice of Action confirming receipt. They usually transfer J-2 applications to Potomac, but we never received the Notice from Potomac later than 1 week to 10 days after we mailed everything off. They usually cash in their check immediately as well.

So far, crickets. And it's making me VERY nervous, considering that processing times are stated at 3.5 to 6 months for Potomac. Our current EAD expires July 31. Two years ago that was missed by THREE days because the card was stuck in the mail and caused all kinds of headaches.

Any fellow J-2s?
Does anyone know whether delays in receiving the Notice of Action with our case number as well as them cashing in the check actually means a delay in actual processing of our renewal application, too?
