And learn their language and customs!

Abide their laws, be courteous, nice and be a "good" citizen ............ should be the same all over the World.

Answer 3

1) You have to follow the country's laws. You'd be no longer on the US soil and if you break a law, there isn't much that the US embassy can do to help you. Keep in mind of your embassy and consulate's phone number in case of emergency.

2) Respect and learn the country's language, culture, and custom.

You'll be fine if you follow those.
