Remember that people abroad have different cultural norms and tend to be less “politically correct” than people in the U.S.
The more you integrate with the culture the less you'll stand out, but your skin, hair, or other features may still attract attention.
Research what kinds of contact and relations your minority group has had in your host country. You may also want to research immigration in general.
Be aware that people may generalize or incorrectly identify your ethnicity.
Learn more about other minority students’ experiences abroad. For example, you can talk to other minority students who have studied abroad or find information online.
Be prepared if an incident does arise, but don't go abroad expecting racism or discrimination.
