The American Citizen Services Section wants to remind all U.S. citizens not to travel outside the United States without a valid U.S. passport.
While dual citizens may be able to travel abroad with alternative documentation, all U.S. citizens are required to present a U.S. passport to re-enter the United States.
We have seen many individuals who have recently naturalized as U.S. citizens travel outside the United States with only their naturalization certificate and/or passport of another nationality be turned away when attempting to reenter the United States.
Your trip could easily be extended as one must schedule an appointment at the U.S. Embassy in Santo Domingo to obtain a passport while in the Dominican Republic.
To avoid delays, obtain your U.S. passport prior to departing for an international trip and verify that the passport will not expire before your return to the United States.
