Chance me for top IR schools please!

A Korean-American seeking to get into a top IR program- Johns Hopkins SAIS/Georgetown MSFS are my dream schools.
Will also apply to Columbia SIPA/Tufts Fletcher/GWU Elliot and mayyyyybe Princeton WWS/Harvard Kennedy School.
Plan to take GRE in late October/November and will submit applications by January 2017 for Sept 2017 admissions.
My concentration in the master’s program will be in Asian Studies/East Asian International Relations or Security…

Here are my stats.

Dual citizen of Korea and the U.S. Speaks both languages as a native speaker.
Undergrad: Top 30 private school on the east coast
International Studies Major / Asian Studies & Economics Minor
Cum laude with a CGPA of 3.63/4.00 but has 2 C+s: Intro to IR & Microeconomic Theory courses… oops… :frowning:
Also withdrew from a non-major course in the second semester of senior year… ugh…
GPA is my biggest concern. Really could have done better at school but let bygone by bygone…

One-Year Study Abroad Program at Waseda University in Tokyo, Japan during 2011-2012
Summer Internships: Consulate-General of Korea in Seattle, Korea Importers Association,
U.S. Embassy Seoul, East Asia Institute
Work Experience: Samsung (Business Development position) for 2.5 years with a focus on overseas business expansion.
Sejong Institute (started as a Research Assistant this summer, a leading IR/diplomacy think tank in Korea) for 6 months by the time I apply. It is non-paid, so I expect it to demonstrate my commitment in the field as I gave up on a high-paying, prestigious job (Samsung is the most popular company to get in among jobseekers in Korea) for a nonpaid position?
Freelancing Korean-English Translator/Interpreter - 3 years… quite well-known on the Korean internet.

Scholarships: David L. Boren Scholarships, Benjamin A. Gilman, Freeman-ASIA, Bridging Scholarships; also received an academic scholarship at Waseda.
Foreign Languages: Native fluency in Korean, Proficient in Japanese, Intermediate in Chinese (took Advanced Japanese & Advanced Chinese), passed the highest level in Japanese Language Proficiency Test with almost a perfect score, multiple Japanese language contest awards.
Some Extra-curricular activities: Orchestra, Asian-American magazine, Japan Club, Study Abroad Advisory Board, Conversation Partners Program… but these are not too special.
Recommendation Letters: one from a PoliSci professor whom I’ve known for 6+ years and taken 4 classes with (he suggested me that he would supervise me for a senior thesis but I declined it because I felt… lazy… do you think I should’ve written one?), another from an Asian Studies professor, and third one from Vice Director (supervisor) at Samsung.

I know that it’s still too early to judge since I haven’t taken the GRE yet. However, assuming that I get a high enough score for GRE, how do my chances look for SAIS/SFS/SIPA and IR fellowships such as Pickering/Rangel, etc?
Also, what more could I do from now on to improve my chances from now on other than writing a solid SOP, getting strong recs and achieving high GRE scores? I would appreciate your responses.

Your experiences make you well suited to those programs. But it is odd that you did badly in the two courses most related to some of your future coursework (IR and econ).
