Slap,

On such poor details I hesitate to be alarmed. If they have been assessed repeatedly before arrival and then taught a skill in the USA - to go AWOL into a 'land of milk and honey' should not come as a shock. If they had all come from one village which had been hit hard, e.g. drone strike then I would have some concerns. I expect they will end up as day labourers or haulage drivers, two occupations Afghans have preferred in the UK and Pakistan respectively.
