Paraguay — Visa & Airports

EU and UK passports enter visa-free for 90 days. US, Canadian, Australian and New Zealand citizens have been subject to a paid visa-on-arrival scheme at ASU airport only (roughly US 60 for Americans, payable in cash, multiple-entry) — the rules have shifted repeatedly, so verify current requirements before booking, and note the visa-on-arrival is not issued at land borders. ASU is the only meaningful international airport, connecting via São Paulo, Buenos Aires, Lima, Santiago and Panama City; overland arrivals at Ciudad del Este or Encarnación must actively seek out the immigration stamp.
