- The one that’s most useful to you. In different phrases, if you happen to aren’t legally obligated to make use of one passport over the opposite, you may determine which to make use of primarily based on the privileges it supplies.

This subsequent step is essential. All the time present your U.S. passport when boarding the aircraft again residence, and present your U.S. passport to frame patrol (or on the World Entry kiosk) upon arrival to the U.S.
