I have studied abroad and the visa application process was fairly simple. It made it easy being a student, not going to work and make money. There is just paperwork to be filled out and documentation that the officials will need. Make sure that you find a good school to be studying through and that your work abroad will transfer back home, if those are your intentions. You don't want to be wasting 4 months of your life studying, doing schoolwork, and going to class and receive no credit for it!
