Moving abroad for dental and/or nursing school

Hi all, I'm in an interesting situation where I have the opportunity to go abroad (most likely Europe) for dental school or possibly nursing school. With all of this I really want to come back to the US to practice and was wondering how feasible that really was.

I'm not too sure where this would be best posted but I figured somebody here may have experienced or heard something in that realm over the course of your travels.

I appreciate any and all insight, thanks strangers!!
