Gallup has also reported that 80+% of Americans favor a path to citizenship for those already here.
The thing is both stat and the title of the thread are probably true. Most Americans when asked what they want on anything want both sides.
A person can want to give citizenship to those already here without wanting increased immigration levels (though I guess someone can argue it's not a workable combination).
Very true and gallup is the most traditional and historical polling. We can support easier paths to citizenship without bringing more people into our country.
