I would not retain this attny. And when you do retain an attny have him/her file an immediate motion so you can get immediate reimbursement of your legal fees.

The recession, lack of equity and all of that good stuff is what it is. I am STUNNED an attny would suggest to you that walking away from the house is a good idea. And a family law attny doesn't need to specialize in immigration law to answer a simple question about the green card. My attny has these handy law books (like thousands of them) that contain all the answers outside of his speciality. If the attny you spoke to y'day is THAT lazy never go back.

So basically your H shook you down for a green card and now will be getting the house, thought he could dictate a future marriage to you, will pay nothing and you pay the legal fees? No. No. No. No. No. No. No.

And NO.

I would go to every divorce attny in your town for two reasons (A) to find the best one and (B) so when you do your H can't have them.

Petition for spousal support and see what happens. And I would be combing over EVERY immigration document I could get my hands on.
