Others will want to share their religious views with you. Most people are sincere and straightforward, but some may try to take advantage of you or convert you to their religious beliefs by offering you their friendship.

Alcohol and Smoking US laws concerning the sale and consumption of alcohol may seem very liberal or very constraining to you, depending on your nationality. In the United States, it is illegal to purchase alcoholic drinks, including beer and wine, until you reach the age of 21.
Laws governing alcohol can vary from state to state.
For example, it is illegal in some states to walk along the street with an open container of beer. Colleges and universities restrict the consumption of alcoholic beverages on campus. Remember that you do not have to drink to act like an American. In many parts of the United States, all public buildings are designated smoke free, meaning that you can not smoke in any part of the building. Other buildings may have spaces designated for smokers.
