Business-immigration to Montenegro.
If you have real estate in Montenegro, that still doesn’t provide you with residence permit. You can apply for a residence permit if you have a company within the country. You can get residence permit if you already have labor permit papers (usually for 1 year, max two years). The costs of legal accompanying: 3000 EUR for an applicant, 1000 EUR – for a family member.
Citizenship and passport.
Montenegro doesn’t accept double citizenship (exception – citizenship granted for investments or based on the ethnical belonging). You can apply for Montenegrin citizenship in case you have legally lived in the country more than 10 years without any intervals longer than 10 months.
