Yes, you must go through this process because your visa will be checked in paperback form on different platforms and by different officers.
In terms of how easy it is to get into the country, Montenegro's visa policy is a lot like that of the Schengen Area. It lets people from all Schengen Annex II countries enter for 90 days without a visa, except for Kiribati, the Marshall Islands, Micronesia, Palau, the Solomon Islands, Tonga, and Tuvalu.
No matter what kind of visa they have, foreigners are not allowed to stay in Montenegro for more than 90 days in a 180-day period. Even if you are from a country that doesn't need a visa to enter Montenegro, this rule stays the same.
