There will always be problem with that kind of set up angelwings.
When you mix your own staff with people whom you think should need a safe house is going to be pretty troublesome.
A similar set-up I think is run under the aegis of the Indian Embassy here where they take care of people(Indians) mistreated by their employers. I think even the Philippines embassy has got some sort of arrangements for this.
When you try to do something on your own make sure you have the full recognition from your embassy, access to lawyers and make sure you dont mix whom you are trying to help out with your own staff.
Whatever good you may try to do will end up creating a lot more troubles if you dont try to leglaise the operations.
