Frequently Asked Questions

Can Singaporean applicants file the Non-Immigrant B (Business) themselves?

Yes, self-filing is possible. Most Singaporean clients still engage professionals because (1) source-country documents require lengthy translation and legalisation, (2) ตม. / กรมการจัดหางาน operates primarily in Thai, and (3) missing documents force restarts that cost far more time than the service fee.

What is the total timeline?

Roughly 4–8 weeks: translation and legalisation from Singapore take 2–4 weeks, then Thai filing at ตม. / กรมการจัดหางาน takes 10–30 business days.

What is the total cost?

Government fees from THB 18,000 + NYC Legal service fee THB 15,000–35,000 depending on complexity + foreign-document legalisation THB 3,000–10,000 depending on volume.

What changes for Singapore documents after 28 Feb 2027?

If Singapore is a Hague member, its documents receive Apostille instead of full legalisation — saving 5–15 business days and THB 1,000–3,000 per document.

Can family members follow?

Yes. The Non-Immigrant B (Business) typically grants Non-O Dependent status for spouse and children under 20, renewable together with the principal visa.

Can I work in Thailand on this visa?

Yes — with a Work Permit filed at the Ministry of Labour (some visas such as LTR and Smart Visa do not require a separate WP).
