It's different for each one.
Let me talk to you about the migrant agricultural worker program, the seasonal agricultural worker program, for example. Others may be able to speak to a live-in caregiver program.
The way it works....There is a memorandum of understanding, as you know, and the workers also have to sign employment contracts when they come in. There is no consultation with the workers before they come in, because the argument is that they do this negotiation with the state governments, though I believe there is sometimes a conflict of interest between the sending country and the worker. Their interests may not always be in line. In terms of the contracts, there is language to say that employers can repatriate, without further compensation, for non-compliance, refusal to work, or any other sufficient reason.
