Overview
About LTR Visa Unit, Thailand Investment and Expat Services Center (TIESC)
The LTR Visa Unit is an official service unit at the Thailand Investment and Expat Services Center (TIESC), on floors 6 and 7 of the One Bangkok Parade building. Its current official website publishes ltr@boi.go.th and 02 209 1109 or 02 209 1110 for enquiries. It is distinct from the SMART Visa Unit, although both use the same centre and published telephone numbers. The LTR website provides its own online application and document-information links, including instructions for visa issuance. Before attending, confirm the stage of your application, the responsible counter, any appointment and the documents or originals required. Follow the current official instructions for the particular service rather than assuming that an enquiry, endorsement application and visa-issuance visit are the same appointment. The mapped office window is Monday–Friday 08:30–16:30, with weekends closed. Confirm the actual counter’s attendance hours and public-holiday arrangements directly.
