Hi, I sent form i-130 for my spouse in March 2018, at that time I was a permanent resident. I received the receipt after a month saying they “received” the file and will notify if they have any updates. By this time, in 1st week of March 2019 I became a U.S citizen and after receiving my naturalization certificate, I sent it to USCIS requesting to upgrade the file for immediate relative. After not receiving any updates from them, I called uscis and found they haven’t received my upgrade package so the officer on call upgraded the file on phone.
After weeks I got a latter saying they have received upgrade request and they’ll process and will let me know if the file is approved or declined. Its been more then a month and I don’t know what’s the status of my file. I called uscis multiple times and they don’t give me any satisfactory response on file upgrade status so does anyone know how much more time uscis/nvc will take on this? Its been 1.5 year since I have filed i130 and they haven’t approved it so I would like to know how much time I have to stay separated from my spouse.
