Do Indonesia passport holders need a visa to visit GT?

Yes, Indonesian ordinary passport holders need a visa to enter Guatemala for tourism. Guatemala places Indonesia in its restricted nationality group, so the consular visa requires prior authorization from Guatemalan immigration (Instituto Guatemalteco de Migracion) before it can be issued. There is no visa-on-arrival or eVisa channel for Indonesian citizens. Indonesia is not among the roughly 86 jurisdictions that Guatemala exempts from visas. Indonesian nationals fall into Guatemala's "Category C" group, meaning a tourist (visitor) visa must be obtained in advance from a Guatemalan diplomatic mission AND requires prior consultation/authorization from Guatemala's immigration authority (Instituto Guatemalteco de Migracion) before issuance. There is no electronic visa, no visa on arrival, and no ETA for Indonesian passport holders. Guatemala is not in the Schengen area, so Schengen and ETIAS rules do not apply. Once granted, a visitor visa generally permits stays of up to 90 days, which are counted across the CA-4 region (Guatemala, El Salvador, Honduras, Nicaragua) collectively. Standard government fees are about US$25 for a single-entry visa and US$50 for a multiple-entry visa. Because there is no Guatemalan resident embassy in Jakarta, applicants typically apply through the Guatemalan mission accredited to Indonesia (commonly handled via Guatemala's embassy in Tokyo, Japan, or another regionally accredited consulate); confirm the correct mission before applying. Travelers should budget extra time because Category C applications need immigration clearance and can take several weeks.
