Just two months ago I was on a mission to Lebanon. I was with a team of 12 trained volunteers and with local partners. I told them that I would pay for dinner for anyone who could find a Yazidi refugee in Jordan, and we couldn't do it.
It shows that in terms of refugee status determination, the UN's mandate is mostly focused on refugees who are outside of their country. They cannot even consider people who are inside their country for refugee status determination. The next step would be resettlement, but because of their mandate they are not able to do that. However, we and some other international organizations, such as the International Organization for Migration or the International Catholic Migration Commission, are worldwide when it comes to referring refugees. It would be very simple to go to northern Iraq and select refugees for resettlement.
