I was holding b1b2 visa and my husband is U.S citizen I cannot apply for green card before for some reasons, the immigration canceled my visa because I have overstay for 18 days and sent me bake home from airport. They told me to get green card to back but the process take to long and I'm pregnant so the process will be more longer if I have my baby out of U.S because she need to have her citizenship to and all this will be without my husband because he can't back to do all of this .What is other way to get back faster than green card ? I just want to back and be with my husband and do all my paper stuff with him . Is there anything to do ?

There is no faster way, I am sorry you were or should have been aware of your time frame, Now you will have to either get a new visa or get citizenship. Perhaps your spouse can move to where you are at for now?
