Здравствуйте! Нужна помощь зала 🙂 как спросиль арендодателя по поводу белого картона на инглише, что бы он понял о чем я )

I need a registration at the address I live at. The white card (бэли картон). Can you provide it please?

(в конце встречи)
Thank you for all your hospitality! I have one more question. According to Serbian law, I have to register my place of stay during the first day in Serbia, and you are obligated to provide the registration to me. Please let me know, when will you give me my приява боравишта странца and how? I will need it the day after tomorrow.
