Q: I am a U.S. citizen/dual citizen(Korea/U.S.) and have been living in Korea. Have I lost my U.S. citizenship by staying away so long?
A: Unless a person voluntarily renounces their U.S. citizenship in person at the Embassy after the age of 18, one does not lose their U.S. citizenship. However, there are certain situations that a U.S. citizen may lose U.S. nationality and please refer to the Department of State website for more information.
Q: My son is a dual citizen and his U.S. passport has already expired. Can my child use his Korean passport to enter the U.S.?
A: U.S. citizens must enter and exit the U.S. with their U.S. passport only. Please apply for a renewal passport as soon as possible. If you have urgent travel plans, the embassy may be able to provide you with an emergency limited validity passport. Please make an appointment, bring all necessary forms and documents, and request an emergency (generally three-month validity) passport during the interview. You will need to bring a flight itinerary to prove the urgency of your travel. Normally, emergency passports can be printed on the same day.
Q: I am a dual citizen. My Korean name in my Korean passport is not the same in my U.S. passport. I will purchase a flight ticket to the U.S. soon. Which name do I have to use when I purchase a ticket?
A: U.S. citizens should travel to the United States on their U.S. passport. Please contact the airlines regarding their regulations on this issue. Please also note that the U.S. Department of Homeland Security Customs and Border Protection (DHS/CBP) is responsible for regulating entry into the U.S. Please contact the DHS/CBP office at the port of entry you will be landing, for more information.
Q: Information on Military Service Obligations for Dual Nationals
All malecitizens of the Republic of Korea (ROK), including dual nationals, have military service responsibilities in accordance with the Korean Constitution and the Military Service Law.
Korea’s Military Manpower Administration is responsible for implementation and enforcement of regulations related to military service responsibilities. The following details related to military service have been provided by Korean officials:
- Males with multiple citizenships must choose their nationality by March 31 of the year they turn 18. Those who fail to do so are subject to military service obligations.
- Male ROK nationals who were born in the ROK but later acquire a foreign citizenship automatically lose their ROK citizenship and are no longer subject to Korean military service, whether or not they notify their loss of nationality to the relevant Korean authorities. However, if these individuals did not abide by military service procedures prior to naturalizing, such as obtaining the necessary overseas travel permits, they may be subject to fines, penalties, and/or incarceration upon return to the ROK.
- All male ROK nationals between the ages 25-37, including dual nationals, must obtain overseas travel permits from the MMA if they have not completed their military service and wish to travel overseas. These permits allow applicants to postpone their military service duty up until the age of 37. Those who lived overseas before age 25, must apply for these permits by January 15 of the year they turn 25. Applications may be made through a Korean embassy or consulate.
- There are different categories under which dual nationals qualify for an overseas travel permit, with classification determined by factors including parents’ citizenship or residency status, time spent abroad, and time spent in Korea.
- In cases where an applicant obtained a travel permit based on their parents’ overseas residency status and the parents have now returned to the ROK, the permit can be cancelled and the applicant subject to military service.
- An overseas travel permit can be cancelled and an applicant subject to military service if an applicant lives in the ROK for at least six months in a period of one year, or has engaged in for-profit activities in the ROK for a total of 60 days or more during a one year period.
