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.

What happens if I overstay?

Fines up to THB 20,000 and blacklisting from 1–10 years depending on length of overstay.

Can I extend at any immigration office?

You must extend at the office covering your registered TM-30 address.

A working guide to immigration-bureau in Thailand

immigration-bureau has been the daily bread of our Bangkok office since 2004. Each matter is opened as a numbered case file that carries the same audit trail — intake note, translator sign-off, attorney jurat, and MFA/embassy stamps — from the first LINE message through to final courier hand-off. Every immigration-bureau matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

How the workflow runs end-to-end

Every deliverable ships with a scanned colour PDF archive alongside the physical original, so the client can lodge with foreign embassies, DHA ImmiAccount, or destination universities the same day the original is dispatched by DHL, FedEx, EMS, or Kerry.

Who this service is for

Individual applicants typically move from first LINE message to signed jurat in under 72 hours; corporate and cross-border matters are quoted on their own SLA depending on volume, destination, and required chain of legalization.

Coverage, fees, and turnaround

International return is handled by DHL Express, FedEx International Priority, or Thailand Post EMS depending on destination and client preference; each option carries a signed proof-of-delivery scan sent to the client's registered email once the pack is received abroad.

Quality assurance and confidentiality

For matters that go before Thai courts, translations are re-certified under the Ministry of Justice's court-listed translator register so the deliverable is admissible as a documentary exhibit under the Civil Procedure Code without a separate hearing on authenticity.
