From an earlier post...
Here is a set of policies that will change this problem:
1. Seal the borders with fences & manpower as necessary
2. Seal the ports and airports against illegal entry
3. Hold all "detained" illegals until deported
4. Re incarcerate all felony convicted illegals into Federal Prisons to be deported at the end of sentence
5. Establish the means to prevent the transfer of funds not associated with international trade out of the country without approval
6. Establish the means to prevent illegals from voting
7. Punish those who employ illegals with large fines/prison
8. No more anchor babies
Problem will go away
Just about every country issues a birth certificate for a baby born there. I don't see how we can avoid issuing a birth certificate.
