Looking for information about green card application after marriage? USAFIS has learned that in this scenario, only you meet both requirements for the Diversity Visa Lottery, so you would submit one application with yourself as the main applicant and your spouse and all unmarried children under the age of 21 (if relevant) as the “derivative” family members and if your application is selected in the DV-Lottery, you and your family members listed in your application will have the opportunity to continue the U.S. immigration process.
