It's not that foreigners aren't welcome. If that were true, we'd just ban foreigners and refuse to issue visas. It's a lot simpler and possibly more unpleasant to think about than that: we don't care about you. Foreign tourism isn't important to us. You don't pay the bills for all this bureaucracy, and he who pays the piper calls the tunes. You don't call the tunes, US taxpayers do.
