Hello I am an Indian national and have a child with a french woman. We enjoy a very good relationship. I am not married to her. Now I want to stay with her and work in france. I am now in India. What should be my next steps?

What is paternity declaration and what are its advantages and disadvantages. I am being advised to declare paternity by her so that I can stay in france and even work there.

Pleasse advise and also let me know a legal french website where I can read more about the immigration laws on a case such as mine.

Thank you.
