English should be a requirement for work visas too.

American employers can pay for their American English lessons, given by American English speaking teachers. Then see how much they save by hiring foreigners.

People who learn "English" in their home countries go through this---

1.) Someone there learns English, but speaks it with an accent.

2.) That person then teaches English with an accent.

3.) Some of those students become English teachers, with the accent they learned, but now have even more of an accent!

4.) Repeats step 3 until nobody can understand WHAT the hell they're saying.
