Questions posed to individuals involved in the process of becoming or supporting a lawful permanent resident can vary significantly from situation to situation. Consular officials and officials of the United States Citizenship and Immigration Services (USCIS) are required to reduce the incidence of fraud and to ensure that the applicants interviewing with them are presenting true and accurate information. Lying or defrauding government officials will prompt fines, criminal penalties and denial or revoking of immigration permissions. Interviews may be conducted for persons for which immigration petitions have been filed and for persons filing a Form I-864, Affidavit of Support, as a sponsor for a foreign national. Commonly, questions at an immigration interview surround the background of the immigrant and his motivations to come to the United States. Special attention is usually applied to verifying marital relationships in order to ensure that the foreign national and the U.S. resident or citizen are actually a couple. Officials may ask small questions pertaining to the applicant's knowledge of his spouse's habits to intimate details of the couples private life.
