I live in Seattle. I am an international grad student in the US. I carry an Indonesian passport. And, I would like to visit Korea for 1 to 2 weeks.
What kind of visa do I need to apply for? How long does it take to process the visa? Do I visit an office in Seattle or do I apply for it online?
According to the official Korean Tourism Organization, you do unfortunately. http://english.visitkorea.or.kr/enu/GK/GK_EN_2_1_1.jsp
However there seems to be a South Korean consulate with visa services in Seattle http://usa-seattle.mofa.go.kr/english/am/usa-seattle/visa/visa/index.jsp
As a side note, I do not think a US student visa grants any special travel exemption as the requirements are generally on your country of citizenship
