According to the interactive map at the link below from Microcosm, from 1820 to 2013 79 million people obtained LAWFUL permanent resident status in the United States. The interactive map below visualizes all of them based on their prior country of residence. The brightness of a country corresponds to its total migration to the U.S. at the given time. Each dot represents 10,000 people.

What is most surprising, I think, is that if you watch carefully the LEGAL immigration coming from Mexico, it does not include ILLEGAL immigration, likely a much larger number than legal immigration. Mexico became America’s number one source of LEGAL immigration in 1960, 57 years ago. Towards the end of the Bush administration and throughout the Obama administration, the broken line on the map showing legal immigrants from Mexico goes to a solid streaming line. The number of illegals in the United States today is estimated as high as 30 million, and as low as 11 million. This means that the number of illegal immigrants from Mexico since the 1960s is a much larger number than anyone has estimated.

Every country has a responsibility to its citizens to control immigration to a point that is economically and socially beneficial to everyone. I no longer include the nations of Europe in that group as their leaders have opened the borders to uncontrolled, unlimited immigration and have hurt their citizens grievously in the process, essentially committing national suicide. If the leaders of the United States do NOT control immigration, it will happen here also.
