Costs of Montenegro Citizenship by Investment Program. Perhaps the most important question besides the other advantages of the Montenegro citizenship program is the question of the costs. There are different types of costs at this point. Donation is the only way to invest in the Montenegro citizenship program. The donation will incur additional costs for the Montenegro Citizenship Program in the form of fees (due diligence, government fee, application fee, lawyer and advisor fee, etc.). Here are some examples of cost development in the area of donation. These examples show the costs for a single applicant, a couple, a family of four and a family of five or more.
