You may need to rephrase a question, check the meaning of something, or repeat what you have said in order to be clearly understood. Try not to misjudge. You will see many things that are different from your own culture. Try to empathize. Try to put yourself in the other person's place, and look at the situation from his or her perspective.
Cultural perspectives can cause very different interpretations of the same situation.
Be open and curious. Try new things, and try to find out how and why certain things are done. The more you explore, the more you'll learn. Don't be afraid to laugh at yourself. It is likely that you will make mistakes as you explore a new culture.
