These are people who hold green cards and who are going back and forth across the border every day, people who live in Mexico and work in California, Arizone, New Mexico and Texas, and also live in Canada and work in U.S. In El Paso, there are thousands of people, probably hundreds of thousands, who have something called a border crossing card. This isn’t 500 million DIFFERENT people, it is 500 million border crossings. It is relatively easy to count heads going back and forth across the bridge.
Try over 4 million. Border Crossing Card (BCC)

Are you sure about that?
I can't figure out how to get this bit of info on my clipboard so I'll just type the information......
quote
"Perhaps, the most important tie connecting our countries is not commerce but people. Every year, our two borders experience 500 million border crossings and the largest source of immigration to the United States in the past three decades has been Mexico-by far.
Nearly thirty percent of all legal immigrants to the United States have come from just one country-Mexico- and nearly 60 percent of all undocumented workers. Canadians move to the United States for both pleasure and work than to any other country. Americans travel more to Mexico and Canada than to any other countries. In brief, our people are connecting the countries routinely and more than ever before. And yet, despite growing interaction, or perhaps because of it, there have been increasing frictions and disappointments among our countries in the past few years."

Now, you said we can keep tabs on those 500 million a year, how's that possible if 60% are undocumented?
We don't know who the hell's in this country.
