How old can you be to move to America?

As long as you move to the United States with your parents, you can be any age at all. You may be able to enter the United States on your own if you have been admitted to a college or university. Any legal adult (older than 18 years) can apply for a visa to enter the United States, but would have to meet a number of other requirements before a Visa would be given. Requirements for moving to Canada, Mexico or other countries in America will be different.
