First of all, you only need to be sponsored by a Chilean company if you are convalidating you ATP. If you are getting your commercial, then you are good to go. You'll have go through the process (painful and costly).
Schickfuss,
I'm sorry to hear you hold so much hatred against gringos. How can you accuse them of racism if you are a racist yourself.
Just so you know, I am Chilean. I live in the US now and I'm looking forward to come back to Chile working for LAN.
Hopefully we'll meet in Santiago on more friendly terms.
