Bulgarian police registration papers checked upon exiting the country?
Apparently there is a rule/law that requires foreigners not staying in hotels to register with the police (and provide proof of registration) upon exiting the country (i.e. at Bourgas international airport).
Does anyone remember how strictly this was enforced the last time you left Bulgaria (and didn't stay in hotels)? I am Canadian, and they had a similar rule in Serbia, but after research online, and advice from others, it became clear it wasn't neccessary to register with the police just because I wasn't going to be staying in hotels during my stay. On the train to Montenegro, no Serbian officers asked for the registration slip, and most people didn't know what registration meant, even though this was written on their embassy website.
How does it work in Bulgaria?
