Touchback amendment next hurdle

Here is Washington Post coverage of the next phase to the immigration debate. Republican supporters of comprehensive immigration reform want to add a touchback provision for all the illegal aliens living in the U.S.
From the story:

Yesterday, the three senators added a provision that would force illegal immigrants to return to their home countries to apply for Z Visas, not just their green cards.

Last week, in the first-ever poll of illegal immigrants, 83 percent of the 1,600 undocumented Latinos surveyed told the polling firm Bendixen & Associates that they would pay the thousands of dollars in fines and fees, produce the work documents and submit to the background check needed for a Z Visa. But if they also had to return to their home countries, participation rates would drop to 63 percent, according to the poll commissioned by New America Media, a consortium of ethnic news media.

TK: Democrats say the immigration bill is tilting to the right, and that could capsize it. However, supporters of the bill are willing to push forward for passage and hope for a favorable conference with the legislation from the House.
