What legalization does United States require?
United States requires MFA legalization followed by attestation at the สถานทูตสหรัฐอเมริกา. Every document we ship carries the issuing authority's full stamp and signature, certified translation by an MFA-recognized translator, MFA consular legalization, and สถานทูตสหรัฐอเมริกา attestation when required.
United States use cases commonly requiring MFA legalization
K-1, K-3, I-130. These use cases require Thai public documents fully processed through the Legalization Chain. Our completed documents are ready to file immediately after all three layers of certification.
Apostille or Legalization Chain — what does United States use?
United States is a Hague Apostille Convention 1961 member, but Thailand is not — so Thai documents go through the Legalization Chain instead of receiving an Apostille. Our Legalization Chain takes slightly longer than Apostille but delivers equivalent legal effect. We get every step right the first time so documents aren't rejected at destination.

Government fees and our service charges
MFA legalization is performed at the Department of Consular Affairs, Chaeng Watthana Soi 19 (opposite the Government Complex) or at regional Passport Service offices. The five core steps: (1) bring the original document already certified by its origin authority (district office, university, DBD, court), (2) confirm whether translation is required first, (3) submit the application form, (4) pay THB 200 per copy (THB 400 express), (5) collect the document with the Department of Consular Affairs red seal.
Differences between Notary, MFA legalization, and embassy attestation
Required documents: original document already certified by the origin agency, certified translation in English or destination language (if needed), translator's certification statement from a registered translator, original Thai national ID card and copy, Power of Attorney with THB 30 stamp duty (if not appearing in person), and a purpose letter from the destination authority.
What a fully legalized document looks like and key fields to verify
MFA government fees are THB 200 per copy for standard (2-business-day return) and THB 400 per copy for express (1-business-day return). Our bundled service fee covers document running, follow-up, translation, embassy submission, and DHL/FedEx shipping — starting at THB 1,500 for simple cases and THB 5,000–10,000 for multi-agency documents.
Languages MFA accepts and list of registered translators
A Notarial Services Attorney certifies signatures, identity, or copies as the first link inside Thailand. MFA Nitikorn certifies that the origin agency's stamp/signature (including the Notary's) is genuine. Embassy Legalization is the final step where the destination embassy authenticates the MFA seal. Documents become usable abroad only after all three layers are complete.
Online queueing and Chaeng Watthana office hours
A fully MFA-legalized document carries the red Department of Consular Affairs seal, the Head of Legalization Section's signature, a reference number, an issue date, and explicit wording stating that only the origin agency's stamp and signature are certified. The reference number can be verified in real time on the MFA online verification system.
Submitting to the destination embassy in Bangkok

Common languages: English, French, German, Chinese, Japanese, Korean, Arabic, Spanish, Italian, Portuguese.
