Can I study abroad for college while in Army reserves?

Step 1) Talk with your NCOs and run it up the Chain

The only way to know is to submit this RFI (Request For Information) thru your Chain of Command/Support Chain. We here on RP have no way of knowing if you can or not. Why? Because you would need permission from your Commander. And none of us can even remotely know/predict what your Commander will say.

Depending on where you intend to study you can report for drill in a few countries. Speak with your COC.

Got with your CoC. Units make allowances for school requirements and real life work requirements. You just have to get with them and let them know so they can do the proper paperwork. It is within their power to mark you as an authorized absence. Similarly they may allow that you can drill over seas if there is a unit in a country you are studying in.

Get with your CoC. No one here at RP will know or really be able to tell you yes or no.
