From Chatgpt:
Yes, in Thailand, the Ministry of the Interior oversees immigration matters. The Department of Immigration, which operates under the Ministry of Interior, is responsible for regulating the entry, stay, and exit of foreigners in Thailand. This department manages visa issuance, work permits, residence permits, and other immigration-related services. Additionally, the Royal Thai Police, under the Ministry of Interior, also plays a significant role in enforcing immigration laws and policies.
This seems to jive with everything I read so far. So Anutin >>>>>> governors and immigration departments
So uh, deputy prime ministers in Thailand have a bit of power.
