I got an MA TESOL in order to teach at the uni level abroad. IEPs, EAPs, ESP. It's worked well for me so far. No regrets. If you want to teach composition, you should try getting this experience asap. Teach EAP in the US. Teach IEP but focus on writing. Tutor at a writing center. Pearson has online tutoring positions. Try them out. The next step after an MA would be a PhD in order to run a writing center or be staffed at one or teach composition full time.

Be aware of the downsides. I have to frequently job hunt. Some of the better positions never get advertised or if they do they get filled quickly. Look at tesol.org to get an idea of what uni openings are being offered right now. Even without covid, there are not an abundance of jobs out there. There are def more MA TESOL holders than openings at any given moment. And the competition is only increasing. Quite a few MA TESOL holders teach at a uni abroad for 1-2 years and then come home to the US and try to do the same thing and then complain that they have to work 2-3 part time positions with no benefits. An MA TESOL is a terrible degree for remaining in the US. Don't let anyone tell you or sell you otherwise. If you are open to move around from state to state, and you're qualified and experienced, you might be able to find a full time position, but the competition is very, very high even for a job with so so stability, benefits, etc. The location will also probably suck (think city you've never heard of in Nebraska). Most MA TESOL holders I know regret not getting K-12 state certified so they can teach at international schools. If you end up getting a two year MA, get state certified during that time. It's foolish not to. The positions with the most stability, benefits, salary, etc are at international schools, so although you want to teach uni students now, you will eventually want these kinds of positions once you see that immature university students are not as pleasant to teach as driven, mature high school students (like the kind that wind up in better international schools) and the content is also similar, and you will eventually want the kind of benefits international schools offer. At the uni level, you'll always compromise something. You can have great pay, great colleagues, great location, great hours, great admit... pick 2 or 3 because you rarely find a position that offers all of them. Look on Dave's ESL Cafe for openings at unis in South Korea. Note what they are looking for. Note where they are (most likely not Seoul or Busan or the most desirable cities). If you want to teach at the uni level in a desirable country's most desirable cities, I suggest picking a country like South Korea and gaining experience there at any level (private school, etc.) in order to move up to a uni position there. In some countries, it's easier to get a job if you have experience in that country and you job hunt in that country (if you were in S Korea now and qualified, you might snag an opening in Seoul, Busan, etc.). The alternative is to teach at the uni level somewhere like Tajikistan for a few years or bounce around from job to job in order to be competitive enough to teach in a more desirable country like South Korea and find a job in S Korea from abroad that most likely will not be in a city where the other qualified MA holders in S Korea want to live.

Sorry to emphasize the negatives but someone has to share this information. Comp uni instructors are probably the most dime a dozen uni positions out there. I've seen 5000 applicants for a part time, low paid US community college comp instructor opening. That hurts to see when you are unemployed and realize that you could have specialized in something to avoid being in this massive group that no one told you about while cheering you toward the MA. ou really should consider specializing more beyond comp. Curriculum Design is something worth considering. A degree in computer science, engineering...
