You can issue a Schengen visa to Hungary for a period of one year if you have a business invitation.

Hungary is a member of the Schengen countries. At the same time, the Hungarian Embassy is quite loyal to tourists and comparatively easily gives long-term visas in the presence of a favorable Schengen visa history.

There are multiple visas (for 90 days, 6 months or 1 year) and multivisa. To request an annual multiple visa or multivisa, you can either with documents confirming the need for multiple trips, or having two or more previously issued Schengen visas. And it is desirable that at least one of these visas was issued in the last year.
