What is a Bulgarian Type D visa and what is it used for?

The Type D visa is Bulgaria's long-stay national visa for third-country nationals whose purpose requires more than 90 days in the country, such as work, study, family reunification or business. It is not itself a residence permit; rather, it is the entry document that allows you to come to Bulgaria and then apply for residence.

There are many distinct grounds on which a Type D visa can be granted, each matched to a long-term purpose of stay. Because it is a gateway document, the ground you choose should line up with the residence permit you intend to apply for once you arrive.
