You may be able to seek annulment or divorce. You have to be careful with annulment that the grounds cannot lead to questions as to whether you entered the marriage in good faith. Once the first marriage is terminated, you could marry again and seek a green card through the second marriage. You will likely face scrutiny. You may need to establish both the current marriage and prior marriage were entered in good faith. The U.S. government could seek to remove you from the country as you are present without valid nonimmigrant status.
