Ummmmmmm....it's federal, has nothing to do with the state you live in.
You are not understanding what we are trying to tell you. Under the I-864 you are NOT obligated to pay her a dime in a divorce. Ever. The I-864 merely states that if she uses any means tested benefits like: Welfare, food stamps, Medicaid ect...that YOU as the petitioner would under the law, have to repay the government for any benefits used. That's it. End of story.
You do not have to pay her a single cent under the obligation of the I864. Period. Full stop. You had a terrible divorce lawyer and you received TERRIBLE advice from an immigration attorney. You got HOSED. Alimony/child support are separate issues that have NOTHING to do with the I-864. Just because you run a software company, is no excuse for not knowing what the I-864 is and means, as far as the law. I'm a dental hygienist, not an attorney, and I understand.
