I arrived...strict airport security didn't let ukrainians go out and took their passports ...4 hours of waiting and by surname they called me in a small room asking about the reason i came there and if i had relatives in Israel...for 5minutes checking I was asked to show my correspondence with the friend who arranged and invited me to come there in Viber , Messager etc...it was unbelievable as i thought noone dare to read my messages...Apart from all clarification i had to retell everything about my work in Ukraine and to describe the plan for these 7 days in Israel. I knew that every detail of my retelling could be checked by phoning to my friend who invited me there.
