A holiday, a job and a course of study in Thailand need different preparations. If you hold a British passport and are travelling for tourism, first see whether your trip qualifies for visa-exempt entry. Work and study cannot simply use tourist entry instead. Decide what you intend to do and how long you want to stay, then prepare the visa appropriate to that purpose.
Visa exemption allows eligible travellers to enter without obtaining a visa first. TDAC is the online arrival declaration. A visa is applied for according to your purpose, such as tourism, study or work. Submitting TDAC does not grant a visa.
London’s current guidance allows British passport holders up to 30 days for tourism from 15 September 2026, subject to the exemption conditions. It states a twice-per-calendar-year limit; ask the embassy about repeated visits because FCDO guidance distinguishes land and air arrivals differently. Other nationalities must check their own rules. Reading an English guide or living in the UK does not make British-passport conditions apply to a different passport.
Start with what you actually plan to do in Thailand, then look for the matching visa category. Thai e-Visa separates tourism, work, study and other purposes. Similar names do not make the eligibility or documents interchangeable. Read the detailed requirements for your intended activity before preparing an application.
Create an account at thaievisa.go.th, complete the form, upload the required documents, pay the applicable fee and submit. Monitor your account and email for further document requests. Once approved, save the visa confirmation sent by email.
London accepts eligible applicants currently resident in the UK, Ireland or UK Territories, with the required immigration status. You must remain physically within its jurisdiction during processing; leaving before a decision can cause cancellation, even though the application is online. British nationality alone does not let someone abroad apply through London. Use the Thai mission responsible for where you are actually staying.
Visa validity is the period during which you can use a visa to enter. Permitted stay is the time you may remain after entry. Even a single-entry tourist visa has separate validity and stay periods.
Receiving a visa does not allow you to remain until its expiry date regardless of arrival. After immigration, use the permitted-stay date in your passport to plan departure. If you need an extension, apply under the relevant procedure before permission expires and await the decision. An application alone does not extend your stay.
No. A tourist who meets the British-passport visa-exemption conditions can enter without a tourist visa. Work, study and other purposes, or a stay outside the exemption conditions, require the appropriate permission. Companions with another nationality must use their own passport rules.
No. DTV covers eligible workcation or Thai soft-power activities, while a tourist visa is for tourism. Read each category’s activity, eligibility and document requirements. London’s DTV permanent-residence and criminal-record requirements are specific to that application route.
London uses Thai e-Visa for applications and confirmations; it no longer accepts physical applications. You must nevertheless qualify for its jurisdiction and remain there during processing. The embassy can require an in-person interview.
