Montenegro visa and entry requirements

The allowance is not your Schengen one

• Montenegro is outside the Schengen area and outside the EU. Its 90 days in 180 are counted separately.
• Days spent here do not consume your Schengen allowance - which makes the region genuinely useful if you are close to your 90-day Schengen limit and want to stay in Europe.
• Your passport is stamped on entry and exit. This country is outside EES, so the stamps are the record and you should keep the passport pages readable.
• Crossing back into the EU re-enters Schengen and is an external border: expect the EES biometric check, and a longer queue than the drive suggests.

Registration within 24 hours

• Every foreign visitor must be registered with the police within 24 hours of arrival.
• Hotels and licensed accommodation do it automatically and give you a slip (the bijeli karton). Keep it.
• Private apartments and informal rentals sometimes do not. If your host does not mention it, ask - the obligation is yours, not theirs, and fines are issued on departure.
• Moving between towns means re-registering at each new address, which again the accommodation normally handles.

Practicalities

• Most Western passports get 90 days.
• Montenegro is a candidate for EU membership and has aligned much of its visa policy with the EU, but it is not in Schengen and its clock is separate.
