OK one prodigy does not mandate the need to amend our entire immigration system. There are millions of really smart people in the world. They don't all deserve a get out of jail free card simply because they can play a board game really well.
My mother was a really really smart motivated and compassionate medical professional. She had to wait in line for nine years to get her naturalization papers because she followed the rules and didn't ask to go to the head of the line.
She probably saved thousands of lives but couldn't play chess worth a damn.
Who asked anyone to amend anything? They're following the appropriate rules.
