U.s border?

Question

If an 18 year old American citizen is crossing the border back into the U.S from Canada does that person need parental consent to go back or can that person go by themself?

Answer 1

they should be able to go back themselves.  Since that person is over 18 they had to have a passport to get into Canada; they will need that passport to get back into the US.

Note: this is what I have been told; I have not done it myself!
