The current EB-5 green card category money requirement is $500k-$1m, and the process is a bit more elaborate.
I don't know where your information is coming from, but the 3 families I tutor their kids are not rich (well, the drug lord kid probably is). They are dentists that practice in Mexico and got the business in order to be able to keep their kids safe here in America and attend schools here as well. They don't have $500,000 much less a million dollars. They are struggling to keep the business afloat by putting in their own money from their businesses in Mexico. Mexico is very unsafe right now and business owners over there are coming and putting their businesses over here because the drug war cartels are using extortion to allow them to keep their businesses going. The meat markets, tortilla factories, and party stores that had their goods in Mexico are now here in Texas with the same store names they had in Mexico. These were our local mom and pop shops over there. Believe me, they don't have that kind of money and yet they are here running their businesses. These are people I knew growing up. They were not rich.
That is why this is so disturbing to me. I didn't notice this until I moved way down south in Texas two years ago. I was living in ignorant bliss in Houston, Texas; a mere 6 hours away from what I see here. It's scary. What my brother said all those years ago started hitting home once I realized just how easy it was to get a green card here. Maybe there is corruption in the lower part of Texas, but that this is going on; it surely is.
Mexico has been really bad for about 5 years, but Central American countries have had it this bad for about 10. That is why the Honduras nationals were becoming Mexican nationals and living in Mexico. Well, Mexico is not safe anymore either. If normal educated folks, and small business owners can get a green card here with about $50,000 or less, I can't imagine some terrorists with money wouldn't try that route, especially with countries like Honduras whose business owners are from the Middle East. What would these people want from such a poor third world country?
Me thinks getting into America's back yard (Mexico) and then just jump in with legal status none the less.
