I'm studying abroad at ISCTE-IUL in Lisbon from late January 2015 to mid-June 2015. I'm currently a U.S. permanent resident with Indonesian citizenship. I'm wondering if there is a Visa that I can get that will allow me to travel freely within the EU during the time that I'll spend at the university. My plan is to probably get a student Eurorail pass and then hit up most of the major countries on the EU side of the continent.
