Is there a way to track information regarding the AOS process online, or to receive updates online like we did with the K1 on the USCIS case status site? For example when the check was cashed with our K1 we could see the case number on the back of the check and registered online. Is this same process offered regarding the AOS process? The check was cashed today but we have yet to receive our NOA1 or Biometrics. We checked the forum and see that this process takes at least 10 days to receive the NOA1. Does this come in the mail?? Anyone with knowledge on this process would be very much appreciated.

Yes, you can track your case online. Its is exactly the same as tracking your K1. But the information may not be available as quickly as it was during your K1 (depending on when you filed). When I filed our K1 (1/07), I was able to use the # on the back of the check and track it as soon as my check image was available, and before the NOA1 arrived. However, when I filed the AOS, it wasn't available for almost 3 months. The checks had been cashed, NOA received, and biometrics were all completed before the case status was available online.
