But as of June 1, Americans will need to present a valid travel document to enter the U.S. from Canada, Mexico, the Caribbean islands and Bermuda. What's a valid travel document? A regular passport, a new passport card, a trusted traveler card or an enhanced driver's license, which states the person's nationality. Children under the age of 16 will not be required to have the travel documentation.
