CNN Presents is doing a story on Nigerian immigrants coming to this country with the intent to commit ID theft and fraud, getting caught and deported, and then coming back AGAIN and doing it all over! They even have organized criminal organizations that are KNOWN to the state department for their criminal activities here. This story they did took place in Houston.
Not only do we have possible terrorists coming across borders, but we have thieves walking right across the borders in Canada and Mexico (that's what they said about how they came here)

One interesting point though was that all those they interviewed who were part of these crimes or who were interviewed about their knowledge of the crimes all spoke perfect English! They are apparently very well educated (the ones caught doing this).

Immigration authorities said after they do their time in prison, they will be deported yet again.....and they just come right back and keep doing it because they said it was "easy money."
