a bipartisan amendment by Sens. Charles Grassley, R-Iowa, Barack Obama, D-Ill., and Max Baucus, D-Mont., ... would change the bill's new program for weeding out illegal employees from U.S. workplaces.

The amendment would free employers from a mandate to check the identities of all their employees and require them to verify only new workers and those the government has a reason to believe are illegal immigrants. It would allow employees to present any state-issued drivers license as proof of identity, rather than requiring the nationally standardized "REAL ID," which some states have not adopted.

The Amendments submitted today are in the Congressional Record here.

For example, Sen. Elizabeth Dole wants to deny Z visas and require mandatory deportation of those convicted of their second DUI offense, even if they were misdemeanors.

Sen. Charles Grassley proposes that:

An applicant for Z nonimmigrant status shall, at the alien’s expense, obtain proper immunizations and undergo an appropriate medical examination that conforms to generally accepted professional standards of medical practice.

and,

PENALTY.—An alien making an initial application for Z nonimmigrant status shall pay a penalty of $5,000, in addition to the processing fee required....

That seems to be a game-plan: raise the cost of remaining in the country so high few will be able to take advantage of it.
