I can't imagine what you feel like...you go through the appropriate channels, abide by the law; then watch everything you worked so hard to achieve handed to criminals on a silver platter.
I was just a kid, but I remember in the Philippines waiting for hours at immigration offices, being interviewed, getting a physical, chest x-rays, and what seemed like dozens of shots (I'm sure it wasn't dozens, but when you're a kid, getting 2 or 3 would seem like dozens). My parents, who came to the US 2 years before we did had to sign a legal affidavit of support.
I remember being SO excited because I was going to come to the states and become an American!
