To live in Korea with your Korean spouse, you need a marriage visa (F-6). The steps are: ① register your marriage in both Korea and Thailand ② get Thai Ministry of Foreign Affairs authentication, Korean embassy consular confirmation and a translation for your Thai documents (Thailand does not use the apostille) ③ apply for the visa after your 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 → get Thai Ministry of Foreign Affairs authentication and Korean embassy consular confirmation → apply for the marriage visa. Your Korean spouse should also take the international marriage guidance program in advance. We take care of the rest.

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
Thailand does not use the apostille yet, so documents for Korea get Thai Ministry of Foreign Affairs authentication and Korean embassy confirmation, in that order. The Apostille Convention is scheduled to take effect for Thailand on February 28, 2027, so the process may change after that.

Going from marriage registration in both Korea and Thailand to the F-6 visa usually costs about KRW 3.5–4.5 million. It differs if there is a history of illegal stay or if income or housing requirements need to be strengthened, so we quote it after reviewing your requirements. Actual costs such as government fees, translation, foreign ministry authentication and consular confirmation 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 your marriage in both countries, your Korean spouse takes the international marriage guidance program, then gets a Visa Issuance Confirmation (사증발급인정서) in Korea, or you apply for the marriage visa (F-6) at the Korean Embassy in Thailand in Bangkok. Once the visa is issued, you enter Korea and complete alien registration (외국인등록).
Your Korean spouse needs a passport, Basic Certificate (기본증명서), Family Relation Certificate (가족관계증명서) and Marriage Relation Certificate (혼인관계증명서) (detailed), a health check certificate, a guidance program completion certificate, income and employment documents, and housing documents. You need a passport, a document confirming single status, birth and family documents, and a health check certificate. Your Thai documents get Thai Ministry of Foreign Affairs authentication and consular confirmation, then are translated into Korean. You both also submit a statement of how you met, plus photos and message records.
Either works. If you are both in Thailand, couples often register at a Thai district office first. If you are in Korea, couples often register in Korea first. The better order depends on your situation, so we decide it first in the free pre-check.
Not right now. Thailand does not use the apostille yet, so documents get Thai Ministry of Foreign Affairs authentication and then Korean embassy consular confirmation. The Apostille Convention is scheduled to take effect for Thailand on February 28, 2027, so we'll check the process after that again in your consultation.
If you register the marriage in Thailand first, the two of you must go to the district office together. If you are in Korea, we can look at registering in Korea first.
First, at the Korean Embassy in Thailand, your Korean spouse has an English affidavit of single status (미혼사실진술서) and a passport copy notarized. These are translated into Thai and legalized by the Thai Ministry of Foreign Affairs. Then the two of you go together to the district office (Amphoe, or Khet in Bangkok) and register the marriage. Some district offices may ask for a Thai witness or an interpreter, so we check in advance. You get the marriage certificate in English, translate it into Korean, and report it to Korea within 3 months.
Yes, the Korean spouse inviting you must take it. Without the completion certificate, the visa application can't move forward, so it's best to take it early in your preparation.
It depends on your history. K-VISA has cases where a spouse with a past stay issue got a marriage visa approved after strengthening the application. We check this first in the pre-check.
If you apply at the Korean Embassy in Thailand in Bangkok, there may be a couple interview. We'll prepare with you in advance so you can both tell the same story about how you met and how you communicate.
Check whether the agency is registered as an immigration application agent, whether it publishes real approved Thai marriage visa cases, whether it can handle local Thai documents (marriage registration and foreign ministry authentication), whether it can communicate with you in Thai, and whether its responsibility if the visa is denied is written in the contract. K-VISA is a registered immigration application agent (No. 19-IC-RG-041) and publishes approved Thai marriage visa cases (4 as of October 2026). We have a business agreement (July 2025) with DS ONLY, an agency designated by the Korean Embassy in Thailand, to prepare local Thai documents together, and we run an express Thai marriage registration package (launched January 2026). We talk with you directly in Thai, and we refund 100% of the fee if the visa is denied due to K-VISA's fault.
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.
