If a thai who has been married to a dane and lived in Denmark , what sort of visa do he need to go back on a visa (multi) ? A tourist ? Or ? A thai that wants to go on holiday in Denmark ?
TLDR : Answer Summary
A Thai citizen who has been married to a Dane and has lived in Denmark may need a Schengen visa to return for a holiday, as Denmark is part of the Schengen area. However, if they have permanent residency in Denmark, they may not need a visa. The entry requirements depend on their current residency status.
