I think it's fair to have concern that some may be coming to the US by the most efficient means possible - which could be to attend and AIDS conference, then blend into the community and not leave at the end of the temporary Visa, and then ride the back of the taxpayer for the approximate $25,000/year AIDS cocktail treatment.
The world knows that this president refuses to enforce immigration laws, and that the stupid Americans are forced to pay for "immigrant" medical care. Bush has rolled out the red carpet, at our expense (again).

I think it would be stupid not to expect it. Of course they will.
