International Document Services

Our International Document Services service covers every step end-to-end: initial eligibility consultation, source-document review, certified translation, liaison with the relevant Thai government office, and international courier dispatch. The handling team includes attorneys registered as Notarial Services Attorneys with the Lawyers Council of Thailand, translators recognized by the Ministry of Justice, and consular liaison officers with 10+ years of experience. Every document carries a different downstream use case — employment, study, immigration, marriage, or commercial filing — and each receiving authority has its own acceptance rules. We plan the shortest and most cost-effective document routing for your case before any fees are charged, and we issue a written timeline so you can schedule your travel or filing with confidence. Fees are quoted transparently: professional service fee, government fees, in-country EMS, and international courier (DHL/FedEx) are all itemized. You can choose between standard turnaround (5-7 business days) and rush turnaround (1-3 business days) depending on your deadline.
