1. Close the borders.
2. Implement eVerify fully- with penalties for managers / owners of scofflaw businesses.
3. Implement an immigration policy to allow educated professionals to enter LEGALLY. Especially young folks who might do us the favor of having babies to replace us Boomers.
4. Allow innocent children of illegals who have graduated from high school (at least) to stay if they demonstrate they can support themselves, or will enter our armed forces. But ensure none of these "dreamers" are allowed to become "anchors" for other family members who do not qualify under step 3 above.
5. Send all remaining illegals HOME, if they do not qualify under 3 or 4 above. Should take about 2 years.
