Are there new passport rules for American citizens?
A. Yes, as of June 1, all Americans reentering the United States will need a single document that shows citizenship and identity. A passport, which costs $100 for adults, is arguably the best choice, since it’s valid for all types of travel. A $45 passport card is valid only for land or sea travel from Canada, Mexico, Bermuda and the Caribbean. Other documents are primarily for travelers who frequently cross the border. Passport applications are available at post offices and online at the State Department. To learn more, go to the Western Hemisphere Travel Initiative website.
