When you’re visiting a foreign country for more than a couple of weeks for vacation, you need to have a visa. Depending on where you’ll be spending your semester, there will be different requirements for a variety of different visa options. Your visa requirements and costs will depend on where you’re staying, how long you’re there and what you’re doing there. For example, if you plan to get a job or internship while abroad, your visa may differ from the typical student visa.
