Good day to everyone!!! For maternity leave/benefits, do we have to go to the TsON according to our registration (propiska)? If you know, please tell me. My registration is in Turkistan Region, I work in Almaty. If I submit documents to the TsON in Turkistan, will a certificate and a sick leave issued by my employer in Almaty be accepted? Or is it better to register my residence in Almaty and submit the documents to the TsON here?
