Well, I know that the government intends to put into place geographic regional quotas. That may not be the best way to approach the situation, especially if you're going to focus on private sponsorship of refugees.
Let people sponsor the people they want to sponsor. Let the public decide that. If there are groups that want to sponsor Eritreans, then let them sponsor Eritreans. Why should we tell them they can't? Especially if it goes towards private sponsorship, it's very easy to do.
