Hi waiting4breakthrough,
I'm the Student Affairs Officer for the Weatherhead East Asian Institute's Master of Arts in Regional Studies-East Asia Program. If you are looking at Korean Studies I would encourage you to apply to our program. With Professors like Charles Armstrong and Theodore Hughes and the Center for Korean Research, our students have access to great professors and conferences. Let me know if you have any questions!
I know there are always questions about the difference in MARSEA, EALAC or LSMA so here's a chart to help: http://www.columbia.edu/cu/weai/ma-programs-summary.html
