Yes. They charge $45 to USA citizens, and similar amounts to citizens of Canada and (I think) Australia. Once you pay this once, they give you a stamped card to staple in your passport so you can use it without paying again for the life of the passport. The reason is because those aforementioned countries charge those same amounts for visas to Chileans going to those countries, so without requiring a visa, they just reciprocate the same fees to the countries that charge their citizens.
