Gallup Poll conducted in early March shows that most Americans support provided a path towards citizenship for undocumented citizens.
"...the majority of Americans, 59%, support the government allowing illegal immigrants to remain in this country and eventually become U.S. citizens if they meet certain requirements. Fifteen percent of Americans support allowing illegal immigrants to stay in the country to work for a limited period of time. About one in four Americans, 24%, say all illegal immigrants should be deported back to their home countries."
"Across the four polls on which Gallup has asked this question since the illegal immigration controversy heated up last spring, most Americans have consistently supported the idea of allowing illegal immigrants to become U.S. citizens after meeting certain requirements. However, slightly fewer Americans favor this idea than did so last year. At the same time, there has been a small uptick in views that the government should deport all illegal immigrants."
