I plan on returning back home to further my education because I think teaching english is something i would enjoy in Korea. Previously I have taught University in China, and have taught children in Korea. I like more developed areas more, but I like teaching adults so getting a Masters seems like the way to go.

I would rather be in school longer to get the MBA because I'm pretty young, 23, and its likely I would like to go back home eventually and I think the MBA is more versatile in that sense. I'm worried the Universities in Korea or Shanghai would prefer a MS in ESOL.

Another option is maybe rush both in 2 years?
