I Japanese undergraduate(B.A.) student with 2.0/4.0 GPA. Since I want to work for ICRC, I'm thinking about getting LLM in somewhere abroad, public international law/IHRL/IHL.

Any chances are I could pass including online learning? I have following some legal-related experiences.

I participated in Nelson Mandela World IHRL Moot Court and Jean-Pictet IHL Competition.
Also I have worked as intern at ICRC national office for a year, and published some legal-related articles for both public and government.

If it seems difficult, I am planing to go national top university first (master of public policy, nobody cares GPA in my countries), getting good grades and apply for LLM as second masters. Or going to Cameroon for two years for work, and then apply hoping international exposure will compensate my undergraduate grades.

I would say if an LLM is your goal, you should at least try to apply now with your current profile.

A low GPA can indeed be problematic, but admission will often depend on many other factors besides that - they'll look at your moots, your internship, and your publication, as well as your TOEFL / IELTS scores.

The grades may be more of a problem at the top schools where admission is most competitive. So perhaps focus on some lower tier options instead.

If you get shot down this year, then yes, perhaps another master's or work experience could help.
