The Philippines is fast becoming the world's low-cost English language teacher - with rapid increases in overseas students coming to learn English or study in English-speaking universities.

There might be other countries that people think about as a classic place to learn English, such as the UK, the US or Australia. But there is one key reason that they are switching to the Philippines. It's much cheaper. And in the competitive market for language students, it means the Philippines is attracting people from countries such as Iran, Libya, Brazil and Russia and other neighbouring East Asian countries.
