So what would I do? I've said before it's easier to complain about something than to fix it. I would have a comprehensive approach to fixing the illegal Immigration problem like the Affordable Care Act's reform of our health care system.
Increase the number of Boarder Patrol agents on the Southern border, so we have enough resources to protect that border adequately. Collect dedicated revenue for Customs and the Border Patrol through a fee charged for border crossings into America from Mexico, Canada, and other countries.
Place steep fines on employers who hire illegal immigrants and pay them below minimum wage. Adjust the amount of the fine for the severity of the violation and the wealth of the company.
Since America is a country where people are expected to work and produce as part of living here and we don't have the resources to subsidize anybody who's not capable of supporting themselves, I would only admit immigrants who are capable of working and qualified to do a job needed here. I would withhold their eligibility for unemployment insurance or welfare until they're citizens of the United States.
Since America is a nation of laws, I'm not for giving the 15M or so illegal immigrants who are in America amnesty for entering our country illegally. That contradicts the Rule of Law but I'm also not for attempting to kick out all of these people because it's simply impractical and inhumane. I would bring these people out of the dark into the light of America and give them a chance at a normal life under the following conditions:
They pay a fine based on the length of time they've been in the country illegally. If they can't pay it at once, installment plans would be available.
They pay all back taxes to Federal, State and local governments that they might have avoided as illegal immigrants, plus penalties and interest.
They become proficient in the English language so they can better assimilate and improve their employment chances.
In addition, illegal immigrants should be required to get a Probational Residency ID Card that would have to be carried on their person like a driver's license and renewed every year. Renewal of the card would be based on their ability to meet the conditions of Probational Residency. If they meet the conditions, they can stay for at least another year. If not, they would be subject to immediate deportation.
These conditions would include a requirement to hold a job or have a private sector sponsor who can support then. After 10 years, if they've met all of the conditions of Probational Residency, they would be granted legal immigrant status and allowed to move towards citizenship. If they've met all conditions except for reparation of back taxes, interest, penalties, and fines, they could remain in the country while their paying off their financial obligations as long as they're not felons and employed. They would be subject to annual review until they reach legal immigrant status.
I think this Comprehensive Approach to solving our illegal immigration problem is more practical and humane than attempting airtight closure of the borders and deportation of15M illegal immigrants.
