I am in the process. My boyfriend and I got married and we're getting our case ready through an immigration attorney to go in front of a judge so they can make a decision on waiving my removal order.
They'll tell you that in the eyes of the law, we are "criminals" so they won't care what we have to contribute. We are petitioning all the hardships my deportation would bring upon my husband, the American citizen. I would highly suggest you find a reputable immigration attorney. Mine is letting me pay in installments.
Good luck! Feel free to PM me with any questions.
