illegal aliens that entered on foot are the only who came in the US without documents or papers. the rest entered america with documents or paper trails, the provisional visas granted to them were privilege, meant to be voluntarily abused by the unsuspecting beneficiaries. legal aliens with temporary visas have premeditated to breach their visas to become illegal aliens. the estimated 30 million illegal aliens, clearly are mixed with mostly hispanics illegally entering the US on foot without paper trails, deserving to be called undocumented illegal aliens. these bunch of breachers of visa privileges, afforded by the US government in good faith have labeled themselves to be called undocumented aliens for respect, part of their propagandas. these breachers should be called DOCUMENTED ILLEGAL ALIENS. no matter how you slice it, what these pro illegal alien propagandists are forcing to the throats of the populous, the fact will not change they are ILLEGALS period. america remain open for legal immigration, americans welcome legal aliens. applicants from around the world are all waiting for decades for the hard to get green cards. mind you, it will be much harder to get green cards for the patiently waiting applicants, with these uncontrollable illegal aliens, like viruses infecting the current government to lost control, a lame duck POTUS, that cannot deport these illegal aliens, to give way for legal aliens.
