Get the passport. It is better and people don't automatically assume you are illegal like they would if you bust out with a Matricula. The matricula is like $27 and my passport was about $90 but it expires in 5 years. I use that to go to bars and clubbing and no one has ever said anything important. I hear comments like is this you? Is it real? Wow this is big? I have never been to a casino with it but I am gald to hear Dreamies do it all the time.
