Timeframe between arrival and cashing my check - Page 2

I got an acceptance email/text on the 27th and they cashed my check the following day on the 28th. I sent mine to Phoenix.

I mailed mine on the 18th. It got there(phoenix) on the 21st. My check was cashed on the 27th.

I sent a personal check. I also sent my package through USPS on the 21st(First class/certified mail). I paid for delivery confirmation which I never received. Last update on usps site shows that my package left a sorting facility in Texas. I got my text and email from USCIS yesterday afternoon. According USCIS site they received my package on the 23rd. Yesterday I checked the bank account and saw 2 pending transaction from USCIS(I sent 2 checks. I for 380 and 1 for 85.).

So 7 days from the day i sent it I got my text email and the checks showed that USCIS was making the withdrawal.

Does it matter which address I sent it to? I sent it to the deerborn address instead of the po box address. My intentions were to send it with a signature confirmation but when I got to the post office I was so nervous that I just let the lady do her thing. I just saw the tracking info and I sent the pachage as priority mail.

I also called the post office and they said the forms have NOT been delivered yet. I now have to wait till the end of the business day today and call again tomorrow if there is no tracking update so they can do some research on my packet -___-
