I'm having a strange situation. I had my combined interview on 03/18 in New York (Brooklyn Field Office). I was told I was approved for both but they couldn't approve me on the same day for both things. Soon after I got an approval letter for my I-751 that said since I'm approved for both they are not sending me a new green card. The consular officer told me it'd be around a month to get the Oath ceremony date and that it would be in NJ (I moved to NJ around the end of this process).
I still haven't gotten any mail and my online account status just says interview scheduled for the N-400, when I called USCIS a rep told me that it was still showing as pending even though they see I passed civics and English. She was very rude and just said they have 120 days to make a decision.
My issue is, I want to travel to my home country for a visit potentially in July, but I have no documents, so I'm wondering, is this even possible with just my I-751 approval letter? Also, anyone have experience with this type of delay?
I thought I was finally done being stressed about immigration but here I am.
