Hi guys
So my wife and I filed the initial forms and today we got the letter in mail (after seeing approval online) stating that the petition has been approved. However, it states that I am NOT eligible for adjustment of status.
Here's a screenshot of the letter: http://i.imgur.com/TpHbmTx.png
Now, I am currently a student in the US. My wife is a permanent resident. The only thing I can think of is that somehow, USCIS thinks I am outside of status and maybe illegally in the US.
Thing with my status is that my student visa expired while I was in the US, but I got a new I-20 from school and never left the US, so I do not have the student visa, but am in status. Not sure if that can mess up my USCIS status.
I scheduled an INFOPASS appointment in 20 days, but wanted to hear if any of you guys had any experience with this issue. I clearly indicated on the application that I want to be processed in the US.
Thank you very much.
p.s. to make things more confusing, I called the USCIS number. The first person I talked to explained that it was a normal procedure, and that my petition was now being sent to NVC (National Visa Center) who will then send me the rest once approved, and that the NOT ELIGIBLE part means that we have to wait for NVC.
I did more research and then called USCIS again, and the second person said that mistake might have been made and to schedule an INFOPASS. So it is very confusing as to what should be done since there is so much different info floating around. Has any of you done F-1 to Permanent Resident adjustment and did you receive a letter like this? Thanks again.
