Thailand to Bangladesh visa requirements

Yes, a visa is required. Thailand ordinary passport holders are NOT on Bangladesh's visa-on-arrival or visa-exemption lists, so a Thai tourist must obtain a visit/tourist visa in advance from the Bangladesh High Commission in Bangkok before travel. A Thailand (TH) ordinary passport holder traveling to Bangladesh (BD) for tourism needs a visa obtained in advance. Bangladesh does operate a Visa on Arrival scheme, but it is restricted to a specific list of nationalities (the US, Canada, Australia, New Zealand, Russia, China, Japan, Singapore, Malaysia, South Korea, the GCC states, Egypt, Turkey, Brunei and European countries) - Thailand is not on that list. Thailand is also absent from Bangladesh's small visa-exempt list (which covers mostly Commonwealth Caribbean, African and Pacific states plus Bhutan and the Maldives). Although a few aggregator sites suggest a visa-on-arrival or short visa-free entry for Thai citizens, the official Bangladesh Special Branch VOA instructions and the Wikipedia visa-policy compilation do not corroborate this, so the conservative and accurate position is that a Thai tourist must apply ahead of time. The application is filed through the online MRV portal (visa.gov.bd) and submitted to the Bangladesh High Commission (Embassy) in Bangkok. The tourist/visit visa is typically issued as single-entry, valid for three months from issue, permitting a stay decided by immigration (commonly up to 30 days for tourism). Bangladesh is in South Asia, not the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply. Bangladesh currently has no online tourist eVisa for general nationalities; the online form is a pre-application that still requires embassy submission and passport endorsement.
