Really? I haven't seen any company here hire workers from the US because this means paying a TON more money. Also bosses here in Mexico sometimes get away with not paying overtime and that can't be allowed with US companies. You must be really needed. If it's close to Mexico city as in driving distance it should be cool, now if you go to the industrial area in the state of Mexico expect boredom when you're not working.
Hopefully you get the call.
Oh you're from canada is it a mining company or something?
