Udon Thani Immigration.

Udon Thani Immigration at a glance

Udon Thani's provincial immigration office has been in the process of relocating away from its long-time Phosi Road address in Mak Khaeng to a newly constructed building in Nong Sam Rong subdistrict, near the Nong Sam Rong Tesaban office, with the move referenced in official announcements around July 2025. This is exactly the kind of change that makes stale addresses linger on expat forums and directory sites long after an office has actually moved, so if you are working from an older guide or a third-party listing, treat the Phosi Road address with caution and confirm the current location before you travel.

Whichever building is currently in use, this remains the single provincial immigration office for Udon Thani, handling 90-day reporting, TM7 tourist-visa extensions, full annual extensions of stay, TM30 address matters, re-entry permits and certificates of residence for residents across the province. For the complete step-by-step process guide -- reporting windows, required documents, fees and overstay rules -- see our dedicated Udon Thani immigration office guide linked below, which deliberately avoids stating a fixed address for the same reason.

Address: The office has relocated, or was in the process of relocating, from its long-standing address on Phosi Road, Tambon Mak Khaeng, Amphoe Mueang, Udon Thani 41000 to a newly built facility in Nong Sam Rong subdistrict, near the Nong Sam Rong Tesaban (sub-district municipality) office. Official announcements referenced a move effective around July 2025. We could not independently confirm the exact new street address and Moo number from an official source at the time of writing, so please verify the current address directly with the office or the immigration website before travelling.
Hours: Historically Monday-Friday, 8:30 AM-4:30 PM with a lunch closure around 12:00-1:00 PM -- confirm current hours for the new location before visiting, since a relocation this significant can come with adjusted hours or a temporary transition period.
Phone: Some directories list 042-249-982-3 for the former Phosi Road office -- we could not confirm whether this number carried over to the new Nong Sam Rong location, so treat it as unconfirmed for the current site.
Getting there: A Grab or metered taxi is the most reliable option regardless of which building is currently in use -- have the Thai address or a pinned map location ready for your driver, since the office has moved and not every driver or map app may reflect the change yet.

Notable facts

• This office has relocated, or was in the process of relocating, from Phosi Road to a new building in Nong Sam Rong subdistrict around 2025 -- several third-party directories still list the old Phosi Road address, which should be treated as outdated.
• We could not independently confirm the exact new street address from an official source -- verify directly with the office or the immigration website before an in-person visit.
