Safety information for study abroad

Remember you are responsible for the choices you make regarding your safety! Be careful all the time. Not knowing about the culture, language, people and situations may put you at higher risk. Learn what women and men do in the culture to protect themselves.

☆ Avoid walking alone at night. Do not agree to meet a person whom you do not know in a lonely place. Be cautious when meeting new people. Don’t give out your address and phone number to strangers or let out too much personal information about yourself.

☆ Do not attract attention to yourself by speaking English loudly in public in America or wearing expensive jewelry. These manners will certainly attract thieves, or worse. Do not be afraid to be impolite when faced with unwanted situations. Do not let anyone push you into taking risks. If you feel unsafe, you probably are.

☆ Taxis are not safe everywhere, especially late at night. Men and women are often robbed by taxi drivers. In many cities, taxis have gotten so dangerous that people use Radio Taxis to get the names of good companies.

☆ When using public telephones, especially in a lonely place, stand facing out so you can see your surroundings. If someone stops you to ask for the time or to ask for directions, step away to a distance that is safer. Why would they consider asking an obviously foreign person for directions?

☆ Your life will always be more important than any of your possessions (财产). Let them go and run away if necessary.
