Singaporean thinking of Chile future

Let me introduce myself. My name is Steve and I am from Singapore. I have been interested in moving myself to Chile and teaching English Language as a foreign language. I am currently undertaking the Master TEFL Diploma and need a few information from you.

1) Average salary for this position
2) Getting a work visa
3) Possible to get a temporary residence visa first without a work visa?
4) For Singaporean passport holders, they only allow 30 days VOA. Will that be a problem?

I would like to thank you in advance for the help rendered above.

Reading through your post I noticed you made several grammatical errors.  My first advice to you is to take some English grammar classes. You shouldn't teach English without a solid background in English language.
