10/22 是receipt notice date, uscis网上查不到这个case,我注意到 uscis 说 "The ability to track case processing is only available to customers whose cases have a receipt number. We manage other cases based on your account number, which is often called an A-number. These start with an "A", followed by an eight or nine digit number. For these cases, you can monitor processing time for the type of case, but you cannot track the processing of your particular case." 难道uscis 用我的A number来审理case了?
