只怕爸爸妈妈数落我...Yup

We have a cousin who is PhD from MIT. (Pure Math).
He used to be able to fly between Europe and U.S. like taking buses. He has worked for some WS firms to design risk models etc for them, though he is not directly employed by them. He could have done his Green Card long long ago, but since he could travel freely he never thought that was necessary - until on one returning trip from Europe, he was REFUSED entry at NYC. After lots of trouble and lots of panic he eventually got back in. But then the regulations have changed a lot, and he can no longer find sponsorship from WS for his Green Card application. He ended up going to teach at a state university in some southern state in order to get his Green Card. Quite a fiasco.
