Hello everyone, I just got my 10 year GC in the mail because the ROC got approved a week before naturalization, but obviously I don't need it anymore since I'm a citizen now and already have done my oath, so my question would be... Do I keep it or contact USCIS somehow so they dispose of it? Anyone else had the same situation in the past? Thanks

I have my n-400 interview this coming thursday but my i-751 got approved out of nowhere just a week ago (I asked for a combo interview since the 751 was pending and was just scheduled for the 400). The problem is that I'm not going to have my permanent card for the interview since it still shows " We ordered your new card." and "Case Was Approved" right after that. Am I still expected to have a combo interview? And whatever the outcome I won't be able to have a same-day oath since I have no GC to hand out right? (My office does same-day oaths if you pass the 400 in the morning)
