Thai Immigration Bureau — Practical Operations
The Immigration Bureau (Sor Tor Mor) is the operational arm of the Immigration Act B.E. 2522 and controls every foreigner's presence in Thailand from arrival to permanent residency. iLC delivers the full ecosystem: 90-day reports, TM-30 residence notification, TM-6 arrival card, re-entry permits (single and multiple), extension of stay (retirement, marriage, work, education, dependents), Certificate of Residence, Certificate of No Criminal Record letter, visa transfer between passports, and complex overstay resolution including departure orders under Section 54. Each transaction has evolved rapidly since 2024's digital push: e-Extension, e-TM-6, and the Digital Arrival Card now coexist with legacy paper forms depending on the immigration office. Our team maintains real-time procedural notes on all 76 provincial offices to route filings efficiently.
