Thailand has reserved certain work for Thai nationals since 1979. The current list is a Ministry of Labour notification under the Foreigners' Working Management decree, which split the old flat ban into groups: some occupations stay closed, some open under international agreements, and some open to a foreigner who is certified as skilled or who works as an employee rather than on their own account. The wording below is the official one, with a plain gloss where the wording is opaque.

The jobs expats ask about

JobStatus for a foreignerBasis
Teaching Englishallowed with a work permitTeaching is on none of the four lists. It is a licensed profession, so under Clause 6 the work permit can be applied for only once the Teachers' Council of Thailand licence or a temporary teaching permit is held; the school normally arranges both. The terms of the temporary permit are not stated in a source The Baht could read. (source)
Tour guideprohibitedList 1, item 22. The official definition covers bringing tourists to locations and providing advice, and running tours with accommodation, food or guiding. (source)
Driver (taxi, van, delivery, boat)prohibitedList 1, item 2: driving as an occupation by road, water or air. The only exceptions are piloting international aircraft and forklift driving. Whether app-based delivery is caught is not addressed by any official statement The Baht found; the wording covers it. (source)
Hairdresser, barber or beauticianprohibitedList 1, item 5. The definition names cutting, perming, washing, dyeing and styling hair, make-up, facial massage and manicure; it excludes equipment preparation, cleaning and foot washing, and film-production make-up under the movie law. (source)
Masseurprohibited for Thai massageList 1, item 20 covers Thai massage as defined under the Thai traditional medicine law, and facial massage sits inside the beauty item. No official statement The Baht found addresses other massage styles. (source)
Estate agent or brokerprohibitedList 1, item 19: intermediary work on commission for insurance, commodities, property sales and lettings or business services. The exception is brokerage in international trade or investment; how far it stretches to foreign property buyers is not defined officially. (source)
Office clerk, receptionist or cashierprohibitedList 1, item 26. The official definition of clerical work includes accounting, reception, receiving and paying money and booking travel tickets, so reception and cashier duties fall inside it. (source)
LawyerprohibitedList 1, item 27, except acting as an arbitrator, or assisting in arbitration where the governing law is not Thai law. Foreign lawyers in Thai firms work as consultants on foreign law, which is outside the listed services. (source)
AccountantconditionalList 2, item 1: allowed only under an international agreement with certification by the accounting professional council, or as occasional internal audit. The clerical definition in List 1 also names accounting, so in-house bookkeeping is exposed to the stricter list. (source)
Civil engineerconditionalList 2, item 2: open to engineers registered under the ASEAN Mutual Recognition Arrangement or licensed under the Engineering law. Only civil engineering is listed; other branches need a work permit and any licence their own law requires. (source)
ArchitectconditionalList 2, item 3: open to ASEAN-MRA architects certified by the Architect Council of Thailand and to licensed controlled architects, under the Council's conditions. (source)
Doctor or nurseallowed with a licence and work permitOn none of the lists. Clause 6 requires the Medical Council or Nursing Council licence before the work permit; the licensing conditions themselves are set by those councils. (source)
Waiter, bartender or hostnot listedNo list names waiting or bar work. The nearest items are shop-front selling (List 4, open only to MoU workers) and clerical work (List 1), whose definition includes handling money and reception, so cashier and front-desk duties are exposed. A work permit is still required. (source)
Remote work for a foreign employerno official statementThe decree defines work as using physical strength or knowledge in an occupation, with or without pay. The BOI's LTR site says no work permit is issued to Work-from-Thailand Professional holders because they work for an employer abroad. No official page The Baht could read states whether DTV holders need a permit. (source)
