Testimonial of Mr. Hong 00 Using Hanguk Visa’s Proxy Visa Documentation Service
A recent client of Hanguk Visa wanted to invite his Vietnamese mother-in-law to Korea with a long-term stay visa.
Many international marriage families living in Korea often need to invite overseas relatives for reasons such as childbirth, childcare, or caregiving.
However, obtaining a long-term stay visa requires strict documentation and clear proof of necessity.
In this article, we introduce the case of Mr. Hong 00 from Wonju, Gangwon-do,
who successfully invited his Vietnamese mother-in-law through Hanguk Visa’s proxy visa documentation service.
[Client Information]
✔Name: Hong 00
✔Nationality: Korean
✔Date of Birth: 1954.04.02
✔Residence: Wonju, Gangwon-do
✔Jurisdiction: Consulate General of the Republic of Korea in Ho Chi Minh City, Vietnam
✔Request: Long-term visa invitation for Vietnamese mother-in-law
Mr. Hong contacted us via KakaoTalk in mid-May after discovering Hanguk Visa on YouTube.
He wished to invite his mother-in-law from Vietnam to support childcare following the birth of his child.
As a busy self-employed resident in Wonju, he did not have enough time to prepare the required documents.
We immediately introduced our Proxy Visa Documentation Service and handled all procedures remotely via KakaoTalk and evening phone consultations.
This service minimizes the client’s burden since Hanguk Visa prepares all required forms
(invitation letter, affidavit of support, statement of purpose, etc.), while the client only needs to provide basic information and signatures.
We prepared and issued all the necessary Korean-side documents on behalf of the client, simplifying the process so that he only needed to provide his signature.
When applying for a long-term family invitation visa (F-1-5), the key is to clearly and convincingly state the reason for invitation.
Short-term visits are relatively easy to obtain, but for long-term stays, a specific and persuasive reason is absolutely required.
In this case, the client’s wife was expecting a baby, and they needed to invite the mother-in-law from Vietnam to Korea to help with postpartum care and newborn childcare.
[Required Documents]
✅ Korean-Side Documents (Prepared by Hanguk Visa)
Items 1–9 were fully prepared, drafted, and issued by us. We also handled printing after receiving photos.
The client only needed to prepare item 10 (Pregnancy Certificate).
1. Invitation Letter
2. Affidavit of Support
3. Statement to Prevent Illegal Stay/Employment
4. Marriage Certificate of Korean husband (detailed)
5. Family Register of Korean husband (detailed)

7. Resident Registration Certificate of Korean husband
8. Copy of Korean husband’s ID card (front & back)
9. Copy of Vietnamese wife’s Alien Registration Card (front & back)
10. Two Pregnancy Certificates (prepared by the client)
When the baby’s due date came earlier than expected,
we quickly replaced the pregnancy certificate with a birth certificate to prevent any issues during visa processing.
All Korean-side documents were prepared, issued, and then mailed to the client,
who only needed to sign them—making the process simple and hassle-free.
The visa application was submitted at the Consulate General of the Republic of Korea in Ho Chi Minh City,
which has jurisdiction over the mother-in-law’s residence.
We also provided a detailed checklist of consulate-specific requirements (ID card, household registration, notarized translations, tuberculosis test, etc.),
ensuring the family in Vietnam could prepare without confusion.
