Correction of paper

I have a paper due tomorrow, discussing a pathway to citizenship for undocumented immigrants. I think my paper is (mostly) grammatically sound, but I need the content slightly altered. The paper often confuses facts and data concerning legal immigrants with undocumented immigrants, and I need that clarified. I need (a) clear editing displaying the actual contributions of undocumented immigrants in particular and (b) the paper's arguments to be sharpened. So the help I need is content-wise editing, nothing too major.
