It costs $12,500 to deport a singleillegal immigration in the United States
“A high-level immigration official says it costs $12,500 to arrest, detain and deport each person removed from the U.S.
Immigration and Customs Enforcement deputy director Kumar Kibble has announced that cost at a House subcommittee hearing. Wednesday’s hearing focused on whether the Obama administration is doing enough to round up people working illegally in the U.S. ICE deported almost 393,000 people from the U.S. in 2010. At $12,500 per person the cost to remove them was almost $5 billion. (emphasis mine)”
Using the estimate of $12,500 per person, it would cost $137.5 billion dollars to deport each and every illegal presently in the country. But of course, even if you deport a large majority of the illegal immigrants, unless we really make a serious effort to secure our border, many of them will come back.
