Chindian Marriage

Hi I am a native of Malappuram, Kerala. My parents and I have settled in Coonoor, Tamil Nadu but I currently work at Bangalore. For a project in China, my team and I had been there for 5 months where we were assisted by a girl translator. After we completed and left back to India, she (translator) texted saying she likes me and want to marry and settle with me in India. I too feel satisfying about her character and marrying her. She is a Cristian and I am a Hindu. We had conveyed our interests to our parents, her dad feels scared to sent her to India but her mom agrees. my mom is also interested but my dad is scared of the issues and consequences in the future legally. In case our parents gets convinced and give us a nod, I want to make sure that we will not have a legal issues living together in India. She is planning to get married here and settle with me in India, what are the steps and will we have a hassle-free life legally? Any religious issues if at all? If we get a child will there be any issues for his/ her future? She will be happy if she could work here, is it possible? What if she/ we wants to visit China may be 3 or 4 times a year? Would be obliged if you can help us out on these doubts and situations we & our parents have. Thank you.
