Pregnant and living home

To make a long story short.
My girlfriend for two years and I became more intimate and she became pregnant this December,She lives with family cristians Belief.
I am responsable for all my acts and willing to marry her and get our place for ourselves.
But the situation is that she cannott leave the house untill she is married. But legal issues cannot let her get married.
she says she is willing to move in and then get married but she is taking back what she had planned in first place.
she feels pressured with her parents decision and mines that I do not want to wait to her to solve the legal issues because this would take more than a year.
I do not want familly to say i was not responsable and have this haunt me in the future.
What can be the best way to solve this problem. Her family already has a negative side about me that happend the unexpected and its been a surprise.
How should I approach this?

I suppose her parents wanted wedding first and children later. You have offered to marry your girlfriend and it is up to her if she wants to. What else can you do?

Be very sensitive to the feelings and needs of your girlfriend and her family. Try to understand their feelings. Show them that you want to do your best in every respect.
