Hello Rookie!!!

I do'nt know if this could help but, I remember awhile back that the Peace Corps were looking for welding instructors to teach in South America...
Did you try contacting the AWS education department?
The State department? Some of the Central American government consulates? just a thought...
Please do'nt take any offense to this next question but, are you fluent in Spanish? The reason why I ask this is because, just having conversational Spanish under your belt will not be enough to teach in these countries. I hope you understand what I mean...
Good luck!!! Please let me and others know what you find out, and if I find out anything new, I'll be in touch!!!

Respectfully,
