Do Hong Kong passport holders need a visa to visit BD?

Yes, a HK SAR passport holder needs a visa for Bangladesh. Apply for a tourist visa at the Bangladesh Consulate General in Hong Kong before you travel. Hong Kong SAR is not on Bangladesh's visa-on-arrival eligibility list, so do not rely on VOA. Holders of the Hong Kong Special Administrative Region passport require a visa to enter Bangladesh for every purpose, including airside transit, as confirmed by the official HKSAR government notice in effect since December 2006. While Bangladesh offers a discretionary visa on arrival to a defined list of nationalities (which includes mainland China/PRC, the US, EU states, Japan, Australia and others), the Hong Kong SAR passport is treated separately and does NOT appear on the visa-on-arrival eligibility list. Bangladesh's own visa-policy classifications place Hong Kong SAR in the "visa required" category. Although a few aggregator sites optimistically describe VOA for Hong Kong, VOA is granted solely at the immigration officer's discretion and is not a reliable channel for HK SAR holders; diplomatic missions universally advise obtaining a visa in advance. The safe and accurate approach is to apply for a tourist (T) visa at the Consulate General of Bangladesh in Hong Kong before departure. Standard processing is roughly 5 working days (3 for express). The applicant needs a passport valid at least 6 months with 2 blank pages, the online application form, two 35x45mm photos, return/onward ticket, hotel booking and proof of funds. Bangladesh is not in the Schengen area, so Schengen 90/180 and ETIAS rules do not apply.
