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. If you begin to feel uncomfortable in such a situation, politely but firmly explain that you are not interested. Alcohol and Smoking U.S. 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. In some states, alcoholic beverages can be purchased only in special, state-run stores. Colleges and universities often have policies that restrict the consumption of alcoholic beverages on campus. Your college or university will be able to inform you of local regulations, so be sure to ask if you are uncertain. Remember that you do not have to drink to act like an American.
