That shouldn't be surprising. Just look at Europe where migrant workers come and don't leave.
If anything the CBO is underestimating those numbers, but either way the notion that amnesty or comprehensive immigration reform is going to do anything about illegal immigration is a joke and a half.
However, the cost estimate of the legislation that was released on Tuesday by the Congressional Budget Office says that the legislation would actually allow the flow of new illegal aliens into the United States to continue at a rate equal to 75 percent of the current rate of illegal immigration. This will be the case, in part, argues CBO, because of people who overstay temporary work visas that will be authorized by the bill.
This revelation that 75 percent of illegal immigration would continue if the Senate immigration reform proposal were enacted is included in a section of the report headlined, “Future Unauthorized Residents.” The section is on page 23 of the 63-page report.
“Unauthorized residents would find it harder both to enter the country and to find employment while unauthorized,” says the report. “However, other aspects of the bill would probably increase the number of unauthorized residents—in particular, people overstaying their visas issued under the new programs for temporary workers."
That shouldn't be surprising. Just look at Europe where migrant workers come and don't leave. Opening the border to temporary workers really dispenses with the need for border crossings. Just come and don't leave.
The government has neither the motivation nor the resources to track even a fraction of the illegal aliens in the country now. Add on a massive amount of guest workers vanishing into sanctuary cities and it will be more like a %175 increase.
