There is no official government list of cooking schools formally āapprovedā for the DTV Soft Power category, but in practice a number of Thai cooking programs are being used successfully because they can provide the documentation embassies look for, such as an enrollment letter, course description, schedule, and proof of legal business registration. Examples that have been used by applicants are mainly in Bangkok and Chiang Mai and typically offer structured programs of several months rather than short tourist classes. What matters is not the school name as such, but that the program is genuine, ongoing, and able to issue proper supporting documents for a DTV application. Requirements and interpretation can vary slightly between embassies, so it is always wise to confirm in advance with the foreign mission where you plan to apply. I am not personally aware of any cooking schools in Pattaya that have been used for this purpose. Prices varies from approximately 20 000 baht for the cheapest six months to 60 000 baht for a twelve month course plus visa fee.
