Before ANY steps can be taken to address the illegal population in the US, the borders must be secured first. If that is not done, then Congress will fail to address the root of this problem. Then the path to citizenship can be addressed, but there should be a penalty for those who entered the country illegally versus legally. The system needs to be reformed for those who are taking the legal steps to become a citizen, so the process is not so long and expensive. Low skill workers should only be allowed when there are also no eligible workers on unemployment who could also fill those positions within the region/state.
