As German passport Holder I can stay 30 Days without Visa in Belarus, I did believe.
After 5 days stay in Minsk I faced very unpleasant surprise at the Airport because I entered the Country without Visa, officer said. He explained that I can enter Belarus without Visa if I come from all countries in the World but not if I come from Russian. I paid 200 US Dollar penalty.
Why Belavia staff in Moscow did not inform me about it?
Why they check me In in Moscow if I do not have Visa?
