Thai Marriage Visa Documents (Non-O Marriage): 2026 Checklist
Complete document list for the Non-Immigrant O Marriage visa, including translations, certifications, and embassy steps for the most common nationalities.
Marrying a Thai national and applying for a Non-Immigrant O Marriage visa requires multiple translated and certified documents. Here is the 2026 checklist used by iLC clients.
Pre-marriage documents
- Single-status affidavit from your embassy in Bangkok
- Passport copy (certified)
- Divorce decree (if applicable) — translated and legalized
- Income proof or bank statement
Translation & MFA
All English-language documents must be translated to Thai by a certified translator and certified at the Thai MFA before Amphoe will register the marriage.
After registration
Apply for the 90-day Non-O at any Thai Immigration office, then convert to a 1-year extension. See our visa country guide for embassy-specific affidavit requirements.
Frequently asked questions
Do I need to translate my single-status affidavit?
Yes. The affidavit from your embassy must be translated into Thai and certified at the Thai MFA before submission to Amphoe.
How much income do I need?
THB 400,000 in a Thai bank account for 2 months OR monthly income of THB 40,000 verified by embassy letter.
Can iLC handle the whole process?
Yes — affidavit translation, MFA certification, Amphoe registration accompaniment, and visa application at Immigration.

Documents usually required
- Freshly issued original Thai civil or corporate record from the issuing office
- Complete English translation of every page, with the translator's statement of accuracy
- Copy of the document holder's passport or Thai national ID card
- Power of attorney with ID copies of both parties if someone else files on your behalf
Common reasons a bundle is rejected
- Each embassy publishes its own checklist; follow the destination's list, not a generic one.
- Supporting evidence should cover the exact period stated on the application.
- Spell every name exactly as it appears in the passport, across every document in the same bundle.
Prefer not to handle the chain yourself? Send the scans and we run every step for you, from translation to the final endorsement.
How the process runs — Visa application document certification
- Obtain a freshly issued original from the office that produced the record and check that every page is present.
- Prepare a complete translation with the translator's statement of accuracy attached.
- File for legalization at the Department of Consular Affairs, Ministry of Foreign Affairs, with the original and the translation together.
- Complete the next certification layer required by the destination country — Apostille, or legalization at that country's embassy in Thailand.
- Collect the finished bundle, scan a full copy for your records, then submit it in the format the receiving authority specifies.
Fees and processing times are set by each authority and vary by document and destination — confirm them with the responsible agency.
Handling it yourself vs letting iLC run it
| Aspect | Doing it yourself | With iLC |
|---|---|---|
| Working out which steps apply | You read each authority's rules yourself, and usually learn a step was missing only after the bundle is refused. | Our advisers review the documents before work starts and sequence translation, notarisation, MFA, and embassy in one pass. |
| Time spent filing | Repeat trips to each office, queueing and collecting in person. | We file on your behalf; you send scans and receive the finished set by post or courier. |
| Risk that the translation is refused | Agency names, job titles, and the certification wording often do not match what the receiving office accepts. | We use terminology and certificate formats the receiving authority has accepted before, with two-stage proof-reading. |
| If the bundle is rejected | You diagnose the cause and refile yourself, losing a full cycle. | We identify the cause, correct it, and refile without you starting over, with progress reported along the way. |
What clients typically use this for
- Visa applications at embassies
- Residency and extension filings
- Sponsor and support evidence
An advisor, not only a document processor
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.
- The certification route is matched to the receiving authority before work begins.
- Rejection risks are checked, from name spelling to document validity windows.
- The filing sequence is planned around the deadline you actually have.
