What's the difference between "tag question" and "~right" which comes in the end of a sentence?
For example, What's the difference between these sentences below?

You're from America, aren't you?
You're from America, right?

Thank you in advance.

"You're from America, right?" I think is heard more than the other. You might ask "Aren't you from America? or Are you an American?"

Both are tag questions. The use of "right?" is more informal.
