"I acquired foreign citizenship — can I get my Korean nationality back?" A foreign national who was once a national of the Republic of Korea can reacquire Korean nationality by obtaining permission for reinstatement. Before that, however, the usual sequence is to settle the loss of nationality and to establish a basis of stay in Korea through F-4 status and the domestic place-of-residence report; whether permission is granted is a discretionary judgment that reviews military service, conduct and related matters.
Acquiring foreign citizenship and the automatic loss of Korean nationality
Where a Korean national voluntarily acquires a foreign nationality, Korean nationality is lost at the moment the foreign nationality is acquired. The loss takes effect at that moment even without any report or notification; the subsequent loss-of-nationality report is not a disposition that extinguishes nationality but a procedure that reflects the loss, which has already occurred, in the domestic records.
If this is left unsettled, however, the person remains recorded as a national in the family relations register and other domestic records. While the records and the actual status diverge, acts premised on being a Korean national — such as using a Korean passport — can become legally problematic, and the person's standing as an overseas Korean cannot be proven, so the preconditions for the later procedures — F-4 and reinstatement — are not in place.
F-4 status and the domestic place-of-residence report
After the loss of nationality, one's standing in Korea continues as that of an overseas Korean. F-4 is the overseas Korean status of stay for persons who once held Korean nationality and their lineal descendants, and the domestic place-of-residence report is the registration procedure for staying long term in Korea on that standing with a basis of life here.
The reason this comes before reinstatement lies in the structure of the procedure. During the review that follows a reinstatement application, a basis for staying in Korea must be maintained, so the usual sequence is to apply for reinstatement after establishing one's standing through F-4 and the residence report.
Requirements and review of reinstatement permission
Reinstatement of nationality is the system by which a foreign national who was once a Korean national reacquires nationality by permission; unlike naturalization, which confers nationality anew, it presupposes the fact of having been a national.
The review may include inquiries into identity, criminal records, military service records and stay history, and permission cannot be granted to a person who has harmed the state or society, a person of unsound conduct, or a person who lost or renounced nationality for the purpose of evading military service. It should be noted that meeting the requirements does not itself guarantee permission; whether permission is granted is a discretionary judgment.
A person granted permission must renounce their foreign nationality within one year of the permission date. However, in certain cases prescribed by law — such as reinstatement for the purpose of permanent return after the age of 65 — a pledge not to exercise the foreign nationality may be made in place of renunciation, allowing dual nationality to be maintained.
What if the dates of birth on US and Korean documents differ
Every stage from settling the loss of nationality to reinstatement proceeds on the recognition that the person in the foreign documents and the person in the Korean register are the same — that is, on the confirmation of identity. A differing name is the type of case that is resolved through the identity-confirmation procedure and an account of how the change came about.
There are cases, for example, where the date of birth on a US certificate of citizenship differs from the entry in the Korean family relations register. A discrepancy in the date of birth goes to the very basis of the judgment that the two records concern the same person, and it is not resolved by the prescribed forms and explanations alone.
In this type of case, the overall schedule and outcome differ according to which country's record is taken as the standard, and in what order the correction of records and the confirmation procedures in Korea are made to interlock. Because the stage the correction has reached affects whether the Korean procedures can begin, arranging the order wrongly can lead to unnecessary waiting or rejection. Where a discrepancy in the records is found, therefore, the very order of correction, reporting and status application becomes a matter of design, and case-by-case review is required.
What to confirm before applying
Taking the above together, it is advisable first to settle the loss of nationality and confirm whether any discrepancy exists in the records — name, date of birth and the like; then to establish a basis of stay through F-4 status and the domestic place-of-residence report; and then to apply for permission for reinstatement of nationality.
