Items may vary depending on individual circumstances:
Additional Documents for Citizenship/Naturalization
When applying for naturalization under the citizenship by marriage program, applicants must submit additional documents:
Foreign nationals married to South Korean citizens who meet the requirements are eligible.
Additionally, those who have been married for at least three years may qualify for simplified naturalization, reducing residency requirements to one year.
Applicants must also demonstrate proficiency in the Korean language and pass a written test on Korean history and culture.
The naturalization process typically takes up to two years, depending on individual circumstances and the efficiency of the application process.
Applicants must complete the necessary residency period and fulfill all requirements before applying.
While the process is structured, it can be challenging due to stringent requirements, including language proficiency, cultural knowledge, and financial stability.
Applicants must also navigate bureaucratic procedures and may face delays.
However, with proper preparation and adherence to guidelines, obtaining citizenship is achievable as it’s not one of the hardest citizenships to get.
Yes, the South Korean passport is among the most powerful globally.
As of 2025, it ranks 2nd worldwide, offering visa-free or visa-on-arrival access to 190 countries and territories, according to the Henley Passport Index.
Arton Capital’s Passport Index ranks South Korea 3rd, highlighting its strong global mobility with a score of 174.
Nomad Capitalist’s Passport Index ranks South Korea at 39th, considering factors beyond travel freedom, such as taxation and global perception.
In summary, while rankings may vary slightly depending on the criteria used, South Korea consistently holds a top position in global passport strength.
South Korea generally does not allow dual citizenship, although exceptions exist for certain categories of people.
The most common case of a Korean dual citizen or multiple national by birth occurs when a person acquires Korean nationality through descent (jus sanguinis) while simultaneously obtaining the nationality of their birth country (jus solis).
For example, a child born in a country that grants citizenship based on birthright, such as the USA or Canada, automatically acquires both the nationality of the birth country and Korean nationality if either parent holds Korean nationality at the time of birth.
This is established under Article 2 of the Nationality Act, which states that a person whose father or mother is a national of the Republic of Korea at the time of birth attains Korean nationality.
In addition to multiple nationalities acquired by birth, some individuals obtain them through acquisition.
These cases include naturalization through marriage, special naturalization via a Korean parent, or special naturalization for individuals who have contributed greatly to the Republic of Korea or to its national interests as outstanding talents.
Multiple nationality may also occur for naturalized individuals who cannot renounce their foreign nationality due to foreign laws, or for persons who recover their Korean nationality through achievement, talent, or after overseas adoption as minors.
Recent reforms introduced more flexibility. Individuals who acquire foreign nationality involuntarily, such as by birth or marriage, may keep their Korean citizenship if they submit a pledge not to exercise foreign nationality in Korea.
If this pledge is violated, the Minister of Justice may require the individual to choose one nationality within six months.
Acts considered violations include repeatedly using a foreign passport to enter Korea, registering as a foreigner, or exercising foreign rights within Korean institutions.
Dual nationals who want to retain both citizenships must file the pledge before age 22, committing to fulfill Korean obligations like taxes and military service.
Male dual citizens must decide by March 31 of the year they turn 18; failure to do so prevents them from renouncing Korean nationality for 20 years, ensuring military service remains binding.
