Yes — Bruneian citizens get 30-day visa-free entry to Cambodia under the ASEAN agreement. You don't need a visa, BUT you DO need the mandatory e-Arrival form filed within 7 days of arrival, now enforced by Royal Brunei, Singapore Airlines, Malaysia Airlines and AirAsia at the Bandar Seri Begawan boarding gate. We handle the e-Arrival filing FREE for ASEAN passport holders — submit your passport and travel dates from Bandar Seri Begawan, Kuala Belait or Seria, and we return the QR-code confirmation by email. Most travellers fly Royal Brunei BWN-SIN-KTI or BWN-KUL-KTI, with the visa-exempt stamp issued at Phnom Penh or Siem Reap immigration on arrival.
There are no direct BWN-KTI flights. Bruneians typically connect via Kuala Lumpur (Royal Brunei + Malaysia Airlines / AirAsia) or Singapore (Singapore Airlines / Scoot) to reach Phnom Penh or Siem Reap. The e-Arrival form is filed once before the final arrival into Cambodia.
Yes. Bruneian visa-free entry applies at Techo International (KTI), Siem Reap-Angkor International, Sihanoukville International airports and at all designated land and river border checkpoints. The e-Arrival form covers all entry modes for ASEAN citizens.
