Combined I-751 and N-400 Approval - traveling?

[lfl 4]

Hello,

 

 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.

Do you still have your expired GC and Extension Letter or is that expired as well?  If you want to travel and the oath has not been scheduled yet, you will need an I551 stamp as the I751 approval letter will not work.

 

Good Luck!
