I know that I have to major in Education, but I don’t know what I have to concentrate in. Also what schools have ESL teacher. Also, do I have to actually learn an Asian language (i’m learning Chinese and in the future Korean)? I’m so confused.
P.S. I live in California.
Yes you should definitely learn the language of whichever country you want to teach in. Imagine if you took Spanish at school but your teacher didn’t know English and taught the whole thing in a language you don’t know 
A major in education, with a concentration in Asian studies and a minor in the language of your choice, would help. Teachers do need diverse skills so don’t be afraid to study something a little different too, like computer science or Econ or something so you would be more employable. Good luck!
@theWriter28 i took a German Class in Germany and it was pretty much all in German
Do you want to live in an Asian country for a long period of time (over 10 years, getting married,etc) or do you want the experience for maybe 1-3 years?
It is VERY EASY to get a job teaching English in Japan or Korea, with minimal to no language and
no specific degree - any college degree is fine. Or no college sometimes.
There are companies that recruit here, and will pay you expenses to fly over and help you get set up. They require a minimum contract, usually a year.
When I was ending my junior year of college (Asian studies major), I decided to take a summer intensive program at International Christian University in Tokyo (ICU). I got a charger flight and lived in a dorm for 2 months. At the end, I hitchhiked to Kyoto where a friend had an apartment. I walked in to one of the many places offering English Lessons, and asked for a job. They couldn’t guarantee me hours, unlike the contracted employees, but they offered me a higher salary due to the fact that I didn’t need airfare and hand holding. I ended up working 9-12, taking Japanese classes in the afternoon, and getting enough evening hours (6-10 PM) to live very comfortably, pay my own tuition, and being home a few thousand dollars at the end of January.
It was amazing. I met a lot of other people teaching english, and the range of ages and reasons was astounding. We called Japan “the Island the misfit toys”, because (foreign) people there tended to be such an odd assortment. It was fun. And easy.
I took this to mean teaching ESL in America, not moving to a foreign country. NJ schools have you double major - my son is elementary ed and history double major. He can take the praxis in history and be certified to teach that as well. I would start at your state U’s and look at what they offer. Also ask your guidance counselor.
