You also are fluent in written English. Is it true (as someone seriously suggested on FR) that it is illegal to teach English in Mexican public schools?
That's a good question. Probably one has to go through the hoops and become a citizen of Mexico. Many Americans can teach sort of like "wetbacks" or undocumented workers and are paid good money in cash. Working for the PUBLIC schools has a lot of labor union built in rules that would make it difficult for an American citizen to teach for pay in Mexico.
