Filed i-130 for my wife exactly 2 years ago back when I was PR; 15 months later I became a citizen. Until now I haven't got any approval/denial about case status of my wife. when I inquire it says, case is delayed or case outside normal processing time. Sometimes they say I should get updates in 45 days, but it's been 3 or 4 times saying 45 days and similar response.

I went to USCIS office and it says it will take time. I have seen some people getting way earlier. I have already updated USCIS, ASAP I became a citizen. I feel like it's taking forever. Has anyone been in similar place? Any inputs will be highly appreciated.
