請問8老師婚姻綠卡的問題， 離婚進行中受到綠卡。

去年問過8老師，我六年前結婚， 他是美國人。在等I-751 過程中，一次吵架，他撤銷I-751，沒有告訴我。導致我麵臨移民法庭。我們又一起file  I-751. After that, he threated to withdraw I-751 again, and had very bad attitude. I filed divorce, and hired a lawyer to terminate my immigration case, but insist on divorce. We signed agreement on separation on this March, but last week, I got my ten-year green card without interview.  My lawyer told immragtion judge and field officer that I filed  adivorce. Do you think that I can keep my green card? Thanks
