The risks of fraud are serious. Applicants who provide incorrect information, conceal relevant facts, or misrepresent their cases may become permanently ineligible to enter the United States. All approved applications are checked against computer records to see if certain information on the application was truthfully presented. It is common in China for an applicant to have relatives in the United States or a petition to immigrate on file. These factors by themselves will not necessarily prevent approval of your application.
