From February 15, 2009, foreigners will be instructed by the Thai Immigration Department to contact the immigration office responsible for the area where they reside.

All changes, extensions, re-entry permits, and other entry applications for Thailand are processed by the relevant immigration authorities in the applicant's district of residence. Please note that immigration authorities at international airports can only process such matters in emergencies such as illness. This also applies to re-entry permit applications, which were previously processed at airports but must now be submitted to the relevant immigration authority in the foreigner's district of residence.

It is recommended to inquire about the immigration office responsible for your specific district. For example, the Kanchanaburi Immigration Office is responsible for immigration matters for the entire province, with the exception of Sangkhlaburi District, which has a separate office. Kanchanaburi is also responsible for immigration matters in Ratchaburi and Suphanburi Provinces.

Nong Khai is responsible for immigration for most of Nong Khai province, with the exception of the districts bordering Laos outside of Nong Khai district, which are handled by the Beung Kan immigration office, along with Udon Thani and Khon Kaen.

Please also note that as of February 15th, the Korat Immigration Bureau will only serve foreigners residing in Korat province, as announced by the Immigration Bureau in Bangkok.

Foreigners living in the provinces of Pathom Thani, Nonthaburi, Chainat, Lopburi, Saraburi, Singburi, Ayutthaya and Angtong can visit either the immigration office in Ayutthaya, the immigration office in Chonburi or the immigration office in Nakhon Pathom.
