More than 300 amendments have been submitted to the Senate Judiciary Committee for possible inclusion in a sweeping immigration reform package – at least 100 from just two Republican senators. But Sens. Charles Grassley of Iowa and Jeff Sessions of Alabama are not the only GOP lawmakers to take a shot at leaving their imprint on the immigration reform effort.

Here are eight of their most notable changes to the bill – from a ban on letting any undocumented immigrants become citizens to policy changes such as how many guest workers should be brought into the United States. The Judiciary panel will be taking up these amendments between now and Memorial Day.
