Do I need a visa to come to Bulgaria for seasonal work?

Nationals of a number of countries do not need a visa for seasonal employment and can be covered by registration carried out by the employer with the Employment Agency. For other third-country nationals, a national long-stay (Type D) visa is required when the stay exceeds 90 days.

Because the requirement turns entirely on your nationality and the length of the engagement, confirm your own situation early. Your employer plays a central role here, since they handle the registration and much of the paperwork, so coordinate with them before booking travel.
