i'm pretty sure it is! English is a universal language. if you do work abroad programs, the main language you need to know is English, however it gives you the opportunity to learn the language of whatever country you go to!
it's possible, yes, but most programs and internships would prefer for workers to know at least some -- if not be fluent -- in the language of the nation in which the worker is seeking work.
lol sorry i should've been more clear. well i will be graduating in medical assistant and i want to be working in like Mexico but i wasnt sure how to search for medical assistant jobs there. i did a bit of research avbout TEFL and TESOL and i was wondering do you have to graduate with some kind of degree in education before taking TEFL/TESOL courses? thanks!
