The U.S. Constitution gives many rights to citizens and non-citizens living in the United States. However, there are some rights the Constitution gives only to citizens, such as the right to vote. You will get the right to vote when you are naturalized. Having a U.S. passport is another benefit of citizenship. A U.S. passport allows citizens the freedom to travel.
Citizens also have U.S. government protection and assistance when abroad.
