Never let study abroad costs get you down. A common misconception of studying abroad is that it's inexpensive, but you know what? There are literally thousands of scholarships and grants out there to study abroad, just waiting for you to apply!
First of all, don't be afraid to reach out to the people around you for assistance. Ask the research office of your university overseas, your professors, the office of financial assistance and your career advisors to remind them about the scholarships or grants they might care about.
