I filed Petition I 130 for my parents in March 2023 and still haven't received any approval from USCIS or the next steps. On the USCIS site, when I check the status it says "Your case is taking longer than expected to process. You will be notified if you need to take any action." Can someone please help me understand how long it usually takes to get through the process? Is there anywhere I can check what's the latest and when I can expect the petition to be approved, case to be submitted for review, medical, etc...
Please help.
