United Nations Refugee Card - Michika Oman U.N. Refugee card: Scammer: Michika Omam or Michika Michika. These are funny. She is a refugee from Sierra Leone but she lives in Brunei. It's about as far from Sierra Leone as one can go. And Brunei is one of the richest countries in the world so why she would even be a refugee is another question. These pictures are recycled.
