To glrao, stonewall, and others who have sent in their applications and are waiting for their check to get cashed and NOA to arrive and it has been more than a week: a word of cheer!
Wife's application sent to Phoenix, AZ and check finally cleared 16 days after delivery to Phoenix Lock Box. That was a very long 2+ weeks of worry.
Here is the background:
My wife and I had sent in our applications in separate envelopes on Feb 3rd, 2010. Each package was tracked and we received delivery confirmation from the USPS that the packages were delivered on the 5th at 10am. My check was cashed on the 11th. I received my NOA on the 15th.
But there was no word on her application. No letter, no nothing. And her check was not cashed. I got worried after another week + passed and there was no word and her check had still not been cashed. We called the customer service line who told us to wait at least 30 days before becoming worried. But with my check already cashed but not hers, and the time-lines on this forum indicating that this first step is usually quick, I just continued to worry.
I see others on the forum now who also are waiting for approx 2 weeks without any word on their application. Well, wanted to let you all know that my wifes check got cashed last night (per the bank). Here is how long it took: Mailed Feb 3rd, delivered Feb 5th, check cashed feb 22nd (16 days later), Bank records updated overnight, found out Feb 23(17 days after delivery, and 20 days after mailing). I have no idea why mine was cleared in a few days and why my wife's took a little over two weeks. The applications were identical, the bank was the same, the post dates and times were the same, etc. Just the luck of the draw, I guess.
Bottom line seems to be that just because your check is not cashed yet and it has been nearly two weeks since you have sent in your app, don't worry yet. The USCIS moves in mysterious ways, their wonders to perform. But honestly, I should hardly crib, given how long the GC or any other process so far has been. The N-400 seems down right instantaneous.
