When I applied concurrently for adjustment os status based on marriage to a US spouse. I received a notification for USCIS that has the receipt numbers for my applications. After couple of weeks I went online to check my cases status and when I change the last digit of my case number I see the updates on my cases. However I do not see any updates using the receipt numbers I received from USCIS at the first time. I am wondering if the updates are related to my cases or to somebody else!!!
