i have been searching on facts about how filipino teachers are faring in singapore. i havent found any single news about it in the internet. am i right in believing that Singapore does not hire Filipino Teachers at all?

There are Filipino teachers in top pre-university institutions such as NUS High School, Raffles Girls Secondary School as well as in tertiary ones such as NUS. The ones I know were already based in Singapore when they applied for teaching jobs. The Ministry of Education seems to prefer local graduates from NUS.

I am a Filipina and I have been to Singapore and Bangkok. Most of our IT specialist and Electronic Engineers are in Singapore. Most of employers personally visit our country to conduct interviews for qualified applicants. They usually conduct this interview in our 5 star hotels and I once accompanied my friend who is an engineer during her interview last year.
About our English teachers most of them are in Bangkok and I am quite surprise when I met some of them, I didn't know that there are many OFWs in Thailand about 15,000 according to our embassy there.
Some others are in Korea ,one parent from school told me. I hope this info helped you in a way.
