United States citizens can enter Montenegro without a visa and stay for up to 90 days. You only need a valid United States passport at the border; immigration officers may still ask for a return or onward ticket, proof of accommodation and enough money for your stay. The 90-day limit usually counts calendar days from your arrival, so book your return flight inside that window.
Whatever your visa status, Montenegro applies the same entry conditions to every traveller:
Montenegro lets 98 passports in without a visa and requires an embassy visa from 100. United States citizens are treated the same way as Antigua and Barbuda, Argentina, Bahamas, Barbados and Brazil. Overall the United States passport ranks #34 in the world with 116 visa-free destinations.
Planning a longer trip in Europe? With a United States passport you can also visit 44 countries in the region without a visa, including Andorra, Albania, Armenia, Austria, Bosnia and Herzegovina, Belgium, Bulgaria and Switzerland.
In the other direction, Montenegro citizens need a visa to visit United States.

Unlawful stay is a stay by a foreigner who does not meet, or no longer meets, the conditions for entry and stay. A foreigner who enters or stays unlawfully, or does not leave immediately or within the time set, is fined 200 to 1,200 euros. The law provides that in the return decision the police, considering each case, may impose an entry and stay ban of at least 30 days and at most five years. An amending law replaces 'may impose' with 'imposes' and '30 days' with '90 days'.
