To live in Korea with your Mongolian spouse, you need a marriage visa (F-6). The steps are: ① register your marriage in both Korea and Mongolia ② get an apostille on your Mongolian documents and translate them into Korean (no embassy consular confirmation needed) ③ apply for the visa after the Korean spouse completes the international marriage guidance program. K-VISA quotes its fee after reviewing your requirements, and we refund 100% of the fee if the visa is denied due to K-VISA's fault.
In short: register your marriage in both countries → apostille and translation → apply for the marriage visa. The Korean spouse must take the international marriage guidance program (국제결혼 안내프로그램), and if you apply at the embassy in Ulaanbaatar, you also prepare for an interview.
In Mongolia, both men and women can marry from 18.

Korean Ministry of Justice F-6 standardsIt looks complicated, but you only need to remember three steps. ① Marriage registration → ② Document certification → ③ Visa application
Mongolia is a member of the Apostille Convention, so a single apostille lets you use documents in other countries without embassy confirmation.

K-VISA's service fee depends on where your spouse is and on your documents and requirements, so we quote it after reviewing your requirements. Actual costs such as government fees, translation and apostilles are separate. Consultation and pre-check are free, and we refund 100% of the fee if the visa is denied due to K-VISA's fault.
After registering the marriage in both countries, the Korean spouse takes the international marriage guidance program (국제결혼 안내프로그램), then either gets a Visa Issuance Confirmation (사증발급인정서) in Korea or applies for the marriage visa (F-6) at the Korean Embassy in Mongolia in Ulaanbaatar. There may be an interview, and once the visa is issued, your spouse enters Korea and completes alien registration.
The Korean spouse needs a passport, basic certificate (기본증명서), family relation certificate (가족관계증명서) and marriage relation certificate (혼인관계증명서) (detailed), a health check certificate, the guidance program completion certificate, income and employment documents, and housing documents. The Mongolian spouse needs a passport, proof of single status, birth documents and a health check certificate. Mongolian documents get an apostille, then are translated into Korean. You also submit a statement of how you met, plus photos and contact records.
Either is possible. If you are both in Mongolia, couples often start in Mongolia; if your spouse is in Korea, they often start in Korea. The better order depends on your situation, so we decide it first in the free pre-check.
No. Mongolia is a member of the Apostille Convention, so you get an apostille and translate the documents into Korean.
You both go to the General Authority for State Registration of Mongolia and register the marriage. Prepare the Korean spouse's documents with a Mongolian translation and apostille, and the Mongolian spouse's identity documents and health check certificate in advance.
Yes, a Korean spouse inviting a Mongolian spouse must take it. Without the completion certificate, the visa application won't move forward, so it's best to take it early in your preparation.
If you apply at the Korean Embassy in Mongolia in Ulaanbaatar, there may be a couple interview. We help you prepare in advance how to explain how you met and how you communicate.
You just need to show that the two of you can talk in a shared language. We decide together in the pre-check which evidence to use.
If you've already registered the marriage, it takes 5–8 weeks on average. If you're starting from marriage registration, it takes about 3–4 months on average (based on K-VISA's working time; immigration review time is separate).
You complete the missing documents or requirements and apply again. And if the visa is denied due to K-VISA's fault, we refund 100% of the fee.
Check that it is a registered immigration application agency (출입국민원 대행기관), that it can handle Mongolian documents (marriage-related certificates, certification, translation), that it speaks a language your spouse can communicate in, and that the contract states the cost and its responsibility if the visa is denied. K-VISA is a registered immigration application agency (No. 19-IC-RG-041) that publishes 50 approved marriage visa cases (as of October 2026), and has organized the marriage registration and marriage visa steps country by country for 20 countries, including Mongolia. We consult in 6 languages, and we refund 100% of the fee if the visa is denied due to K-VISA's fault.
