F6 visa citizenship, In recent years, international marriages have been steadily increasing. Foreign nationals who marry Korean citizens are granted an F-6 Marriage Immigrant Visa. However, since this visa has a limited period of stay, many individuals consider either obtaining permanent residency (F-5) or naturalization (Korean citizenship).
Recently, more applicants are choosing naturalization, so this article provides a clear summary of the requirements for simplified naturalization.
Legal Basis: Article 6, Paragraph 2 of the Nationality Act
The legal basis for simplified naturalization is Article 6(2) of the Korean Nationality Act.
This provision states that:
A foreigner whose spouse is a Korean national may be granted naturalization without fulfilling the requirements of Article 5(1) and (1-2), provided they meet one of the following conditions.
The requirements under Article 5(1) and (1-2) include:
- Maintaining continuous residence in Korea for at least 5 years
- Holding a permanent residency status (F-5)
Since the Korean Nationality Act generally adopts the principle of requiring permanent residency prior to naturalization, this provision creates an exception for spouses of Korean nationals.
Therefore, even without permanent residency, a foreign spouse may apply for naturalization if they:
- Maintain a valid marital relationship and
- Have resided continuously in Korea for at least 2 years
This effectively allows applicants to skip the lengthy process of obtaining permanent residency, which typically involves:
- 5 years of residence
- Passing the permanent residency evaluation (종합평가)
This exception can be considered a significant benefit.
Residency Requirements for Marriage-Based Simplified Naturalization
Applicants must maintain a valid legal marriage (not a de facto relationship) with their Korean spouse until the naturalization approval.
Residency requirements are as follows:
- Reside continuously in Korea for at least 2 years after marriage and foreign registration, OR
- After 3 years from the date of marriage, reside in Korea for at least 1 continuous year
Requirement of Good Conduct
Applicants must demonstrate good moral character, meaning:
- Compliance with Korean laws
- No criminal record, or
- Sufficient time has passed since completion of any sentence
Even if there are legal violations, the Minister of Justice may still recognize good conduct by considering:
- Circumstances of the offense
- Degree of harm to public interest
- Contribution to Korean society
- Humanitarian considerations
Financial Stability Requirement
Applicants must demonstrate the ability to maintain a stable livelihood.
This can be satisfied through:
- Personal income or assets, OR
- Financial support from family members
“Family members” include:
- Spouse
- Direct relatives (parents, children)
- Siblings
This definition also extends to:
- Spouses of direct relatives
- Spouse’s direct relatives
- Spouse’s siblings
Korea Immigration & Integration Program (KIIP) and Interview
One of the greatest benefits of marriage-based simplified naturalization is that:
👉 The KIIP comprehensive evaluation (written test) is exempt.
However:
- The interview assessment is mandatory
In certain cases, even the interview may be exempt, such as:
- Applicants under age 15
- Spouses of restored Korean nationals (age 60+)
- KIIP comprehensive test passers
- Individuals with special merit to Korea
- Descendants of independence activists or national contributors (age 60+)
Required Documents
