Non USA passport holders should check to see if a visa is required for their nationality here: http://en.wikipedia.org/wiki/Visa_policy_of_Chile

Applicants may have to pick up the passport directly from the Chicago consulate as they need to sign a document once the visa is issued.  SPS will contact you if they are unable to pick up your pssport and issued visa

Visa Applications must be submitted in the proper jurisdiction, jurisdiction is determined by where you reside.  Please note that you must appear in person for your visa unless you live in the Chicago jurisdiction.  If you do not live in the Chicago jurisdiction, please visit the Embassy of Chile website for more information.
