U.S. Laws You Should Know

While you are in the United States, you must follow federal, state, and local laws. These laws may be different from those in your home country. Violating a law can affect your immigration status, even for minor offenses.

You are responsible for understanding and following these laws. If you have concerns, Visa and Immigration Services (VIS) can provide confidential guidance and refer you to legal resources.

If you need support, contact VIS at vis@stonybrook.edu.

Alcohol and Drinking Laws

• You must be 21 years old to drink alcohol.
• You cannot buy alcohol for anyone under 21.
• The legal limit for driving is 0.08 blood alcohol concentration (BAC).

If you drink alcohol, do not drive. Use public transportation, a ride service, or a designated driver.

Drug Use

• In New York State, marijuana is legal for adults 21 and older.
