Vietnam to Montenegro visa requirements

Yes, a visa is required. Holders of an ordinary Vietnamese passport must obtain a Montenegro short-stay (Type C) visa before travel, applied for at a Montenegrin diplomatic mission (the embassy in Beijing serves Vietnam, as there is none in Hanoi). Montenegro's visa-free exemption for Vietnam applies only to diplomatic, official and service (non-ordinary) passports for up to 30 days, not to ordinary tourists. The one common shortcut: if you already hold a valid Schengen, US, UK or Irish visa or residence permit, you may enter Montenegro visa-free for up to 30 days. Montenegro is not in the Schengen Area, so the Schengen 90/180 rule and ETIAS do not apply. Montenegro is an EU candidate that aligns its visa policy with the EU but is NOT part of the Schengen Area; it uses the euro and ETIAS does not apply to it. Under Montenegro's visa decree, Vietnam is listed only in the non-ordinary (diplomatic/official/service) passport exemption category for 30 days. Ordinary Vietnamese passport holders therefore need a visa for tourism. Several visa-information aggregators incorrectly state "90 days visa-free for Vietnamese," conflating the non-ordinary-passport exemption with ordinary tourist travel; authoritative sources (Wikipedia's mirror of the MFA decree, the visit-montenegro list which omits Vietnam, and doyouneedvisa) confirm a visa is required for ordinary passports. The practical exception, written into Montenegrin law, is that holders of a valid Schengen, Australian, Japanese, Canadian, New Zealand, Irish, US or UK visa or residence permit may enter and stay up to 30 days without a Montenegrin visa. Montenegro does not operate an eVisa or visa-on-arrival scheme, so an ordinary Vietnamese traveler without one of those qualifying visas must apply in person/by mail at a Montenegrin embassy or consulate (nearest serving Vietnam is in Beijing) for a Type C short-stay visa, which costs roughly EUR 35. Recommended approach for most travelers: if you hold a multiple-entry Schengen visa, use the 30-day visa-free entry; otherwise apply for the Type C visa well in advance.
