I would have a problem with that too. There may be cases where a temporary foreign worker then qualifies for permanent residence here. I think there is some provision for that. But it's true, you can't let them stay indefinitely; you're going to have social and other kinds of problems. So that has to be dealt with.
Just to summarize my thoughts very briefly, we do need to do more research on this. We have to have a clearer picture. We should see what other countries have done and where it doesn't work, because we've suddenly gone into this massively expanded program, and I think there are problems. We really should be looking at them more carefully.
