Hi. I am from the Philippines and I speak Filipino. However, English is the medium of instruction in schools here, so most Filipinos can speak good English -- or can at least understand English very well, as there are still those who practice wrong grammar when speaking and writing.
Anyway, I also am considering teaching English as a second language, because I want more and more people to speak English fluently. English is known as the international language, so it really helps if we know how to use it.
