Some perhaps, yet the powers that be, in their infinite wisdom, required only 2 years of residency - and I suspect they required little, if any, proof - to qualify for "refugee" status.
The temptation for potential "refugees" to cash in on "three hots and a cot" and the relief agency's desire to justify their existence and their budget, I'd say provides ample opportunity and motivation for fraud.
