An individual can enter the Schengen Area as a whole for up to 90 days without a visa if he/she:^[63]

• holds a valid travel document, and
• possesses a residence permit indicating that the person is a family member of an EU/Schengen national, and
• is travelling together with or joining an EU/Schengen family member.

A family member of an EU/Schengen national satisfying the above conditions can also enter Bulgaria,^[64] Croatia, Cyprus^[65] and Romania^[66] and stay for up to 90 days in each country.

In theory, a family member of an EU/Schengen national who does not fulfil the above conditions does not have to apply for a visa in advance, and can instead obtain a visa on arrival at the border checkpoint of a Schengen country, Bulgaria, Croatia, Cyprus or Romania by presenting evidence of the familial relationship.^[63]
