Obviously not. An increasingly larger percentage of illegal aliens gain entry through birth on US soil. These aliens, while subject to deportation, are afforded certain protections by a recent Supreme Court decision (1982) and don't show up in the statistics because we've eliminated the neighborhood sweeps.
But ... illegal immigration (by birth and trespass) has been increasing steadily since 911.
Sorry, but Plyler v. Doe had to do with public education rights for illegal aliens, not birth rights.
The current birthrights are written into US Constitution, and have yet to be argued in the Supreme Court. Although it will be soon.
So, no illegal aliens gain entry by birth.
