PERM still not approved after 18 months—should I be worried?

My employer filed my PERM on July 27, 2023, and I still haven’t received any updates. It’s now January 2025, and I’m getting really concerned since this seems like an unusually long wait. I do have a case number and when I go to DOL site it says - analyst review

Has anyone else experienced such a long delay recently? Is there anything I can do to check the status or escalate the case? Any advice would be greatly appreciated!

Thank you
