I'm in the same boat as you. I planned to study abroad in the fall then come back and graduate in the spring. Thankfully, my uni hasn't canceled travel for the fall yet but it's still likely. What I was told is possible is remaining matriculated even after graduation. So you could graduate in the spring, and just receive your diploma after you come back. But I would talk to your study abroad advisor if that's possible for your uni. Good luck and keep us updated!
