Refugee status should NEVER be permanent. It must always be a temporary protection for people when the situation in their home country is fucked. During this time, refugees should be able to learn skills from their host countries (as far as they are able to), so they should be tested when they arrive and then trained for whatever they are capable of (no point trying to train a 65 IQ african to be a surgeon, but he could be ... umm, probably nothing actually. Anyway, you might be able to train someone with an 80+ IQ to be a builder or plumber, skills that their home country, being fucked, would need). Once the conflict or whatever is over, they MUST return home, with any fucking kids they popped out in the mean time. All refugees should remain isolated from the wider community, not integrated, and MUST not be allowed to get around the return requirement for any reason (i.e. marying a local would not allow them to stay, they and any children must return).
