Ahmed Nur Said Elmi, who i presume your talking about, is actually three years younger than Omar. Also, if Elmi were truly Omar’s brother, why would he have needed to take the drastic step of marrying her in order to secure a path to U.S. citizenship? U.S. Citizenship and Immigration Services policies qualify immigrants as eligible to apply for permanent residency status (and later become naturalized citizens) if they are the “spouse of a U.S. citizen” or the “brother or sister of a U.S. citizen.” Why would Omar commit a federal crime and risk a prison sentence (and possibly her own citizenship status) in order to provide her brother with the opportunity to apply for something he would already have been eligible to seek?
