Thailand’s 30-day visa exemption leaves treatment travellers’ status unclear

Thailand’s new visa-exemption rules allow Dutch passport holders to stay for up to 30 days without a visa for tourism, but the government says people entering for other purposes must follow the rules for the relevant visa category. That leaves a key question unanswered for Dutch people considering residential addiction treatment there: whether treatment qualifies for the tourism exemption, and what visa they need for a longer stay.

The revised rules took effect on 15 September 2026, replacing the former 60-day exemption. The Netherlands is among 60 countries and territories covered by the 30-day tourism scheme, according to Thailand’s government and tourism authority [1] [2].

Thailand’s government says the exemption measures apply to tourism and that visitors travelling for other purposes must consult the relevant visa category and regulations [1]. Its published guidance does not say whether residential treatment is covered or specify the visa or extension arrangements for someone entering Thailand for that reason.

The change matters to people planning treatment lasting longer than a month. A Dutch-language guide published by Nieuws.nl says stays of eight or 12 weeks exceed the visa-free period and advises prospective patients to ask clinics about extensions or another visa [3]. But the official guidance cited here does not confirm that such an extension or alternative is available for treatment.

The tourism authority says Dutch passport holders can stay for up to 30 days under the exemption for tourism [2]. Anyone considering treatment should check the applicable entry rules with Thai authorities before travelling, rather than assume that a tourism exemption covers a clinical stay.
