Do United Kingdom passport holders need a visa to visit MM?

UK ordinary passport holders need a visa for Myanmar and must apply online for a tourist eVisa before travel — visa on arrival is not available. The eVisa costs USD 50, allows a single entry with a 28-day stay, and must be printed and presented at the border. A British (GB) ordinary passport holder visiting Myanmar (MM) for tourism must obtain a tourist eVisa in advance through the official Myanmar government portal (evisa.moip.gov.mm). The UK FCDO is explicit that a visa is mandatory and that visa on arrival is not available, so travelers must apply and receive approval before departure. The tourist eVisa is single-entry, valid for 90 days from the date of issue (i.e., you must enter within 90 days), and permits a stay of up to 28 days from arrival. The government fee is USD 50, payable online by card or Alipay. Standard processing is up to 3 working days, with a Tourist Express service available in about 24 hours. The eVisa is accepted at 3 international airports (Yangon, Mandalay, Nay Pyi Taw) and 5 designated land border checkpoints (Tachileik, Myawaddy, Kawthaung, Tamu, Rih Khaw Dar). The passport must be valid for at least 6 months on arrival. The approval letter must be printed and shown at check-in and immigration. Note that Myanmar remains under conflict-related travel restrictions; the FCDO advises against travel to many areas, so travelers should check current FCDO advice before booking. Myanmar is not in the Schengen area, so Schengen/ETIAS rules do not apply.
