PASSPORTS: U.S. citizens who travel to a country where a valid U.S. passport is not required will need documentary evidence of their U.S. citizenship and identity. Proof of U.S. citizenship includes an expired U.S. passport or an original birth certificate. A certified copy of the birth certificate is also acceptable, but it must have the registrar’s signature and a raised, impressed, embossed, or multicolored seal. If you were born abroad, a Certificate of Naturalization, Certificate of Citizenship, or Report of Birth Abroad of a Citizen of the United States will suffice. To prove identity, a valid driver’s license or government identification card are acceptable provided they identify you by physical description or photograph. However, for travel overseas and to facilitate reentry into the U.S., a valid U.S. passport is the best documentation available and unquestionably proves your U.S. citizenship. Before you send your passport through the mail to apply for a visa, sign it in ink, and write in pencil your current address and daytime telephone number in the space provided. This will help the U.S. Postal Service return it to you should it become separated from the envelope during processing.
Some countries require that your U.S. passport be valid at least 6 months or longer beyond the dates of your trip. If your passport expires before the required validity, you will have to apply for a new one. Please check with the Embassy or nearest Consulate of the country that you plan to visit for their requirements.
