being in bc you just get a nice view of the situation. i believe in your country illegal immigration is taken care of through the healtcare system? no id, probably no healthcare and deported? shouldn't throw stones when you live in a glass house lib. your thoughts are just like mexico's - look at their immigrant situation/laws and you will see the US is, even now (even though it is just a old fed law being enforced) is much more lax than mexico's. but i doubt you have read the AZ law let alone the Mexican ones.
the teacher situation isn't about any particular accent, basically all. in your opinion it is ok to teach even though you can't speak the correct language in a manner in which people can understand you?
i believe AZ is also in the process of not making biz give info out in languages other than english - i am sure you will have a problem w/ that too
