To combat the potential for fraud in marriage cases, the United States offers conditional status to the immigrating spouse in recent marriages and reviews the case after two years to make sure that the marriage is valid before granting permanent status.
为防止发生婚姻欺骗情况，美国对新近结婚的移民配偶只给予有条件身份，并在两年后对其复审，以确保此婚姻在颁发永久身份之前有效。
