Requirements to teach at secondary level at international schools

I realise the local education system requires different accomplishments and was wondering what is required in order to teach at GCSE/IB level at International Schools here. I myself have graduated from an International School here and would love to teach there in the future.

As a Korean citizen with a Singapore PR, with a Bachelor’s degree in Fine arts from the US, is a post undergrad degree crucial in securing a position?

You need certification as a teacher from somewhere in addition to a bachelors or masters. Hint: you can get this online. It also helps to have some teaching experience.
