Marrying an muslim (islamic) Syrian girl to an indian Hindu male.

Hello All, I'm an hindu Indian , I have an girlfriend at turkey (Islamic) ,but she is a citizen of syria. I have some questions that arise in my mind when I read about this kind of marriage. 1.) As per syrian law Interfaith marriage is prohibited that a muslim men can marry an non muslim women but the vice versa of it marrying an non muslim men to an muslim women is not allowed. 2.) In india I came to know this interfaith marriage is valid under special marriage act 1954. 3.) In islamic also its not allowed to marry an non muslim person to an muslim women. As its treat as sin. My question is without converting our respective religion like I will follow the Hinduism and the Syrian girlfriend can follow islamic religion. Can we get married now via valid laws. If yes what are the procedure she and I have to follow up for doing this marriage. Either in india or other countries . If she is getting married to a non muslim man like me is it a valid one or a invalid one, can we get a marriage registration certificate. Does she have to give up her syrian citizenship if she wants to marry me. Are there any non objection certificate to be provided from her side by the Syrian government. If yes what are the procedure to get it with respect to this kind of religion different marriage. It will be helpful if I'm getting an clear idea to proceed further. What is the things and steps required for doing this kind of interfaith civil marriage via valid law suit. Thank you.
