Your withdrawing a petition does not insulate you from a finding of fraud. In some instances, it can make the matter worse. Your wife will have no legal status of right to remain in the country. Her work permit will become null and void upon issuance of a decision denying her green card application. Your wife could find herself in removal proceedings. I encourage you to work with an attorney if your goal is to keep your wife in the country and acquire status for her.
