美国人依赖的30天免费旅游自动延期已于2025年11月结束。以下是原规则内容、替代规则,以及2026年美国公民在柬埔寨停留超过30天的可行方式。

No — not the way you used to. The tourist eVisa auto-extension that handed Americans a near-automatic extra 30 days ended in November 2025. A Cambodia tourist eVisa now gives you a hard 30-day single-entry stay, and there is no in-country path to extend it for more tourism time. If you need longer than 30 days, the realistic route is the Business (Type E) eVisa, which is the only Cambodia visa class you can extend from inside the country. For a separate later trip, you apply for a brand-new tourist eVisa — each one is a clean 30-day single entry, valid for 3 months from issue.
This guide explains exactly what the old rule was, what replaced it, and the realistic ways an American stays in Cambodia beyond 30 days in 2026. If your trip fits inside 30 days you can stop reading and apply — most US travelers finish in a few minutes. Our Cambodia visa for United States citizens hub pulls the cost, documents, and processing timeline into one place.

Overstaying is the worst way to handle this, and it is entirely avoidable with a little planning. If you are weighing how tight your dates are, our breakdown of how long US citizens can stay in Cambodia walks through the 30-day clock and the validity window in detail, and our note on Cambodia overstay fines for US travelers shows exactly what a miscalculated exit costs per day.

The mechanics of the in-country extension — the duration blocks, what each one costs, and how the multiple-entry conversion works — sit in two companion guides. Our walkthrough of Cambodia visa extension cost for Americans covers the pricing of each extension block, and the Cambodia Ordinary (E-Class) visa explained for Americans maps the EB, EG, ER, and ES sub-classes you extend into for work, retirement, or study.

If the come-and-go pattern is your situation, it is worth understanding the single-entry rule properly before you book flights that cross the border twice. Our guide to single-entry vs multiple-entry Cambodia visas for Americans lays out exactly when a second tourist eVisa beats reaching for the multiple-entry Business track, so you are not paying for re-entry rights you will not use.

Here is the whole thing in one line: the old tourist auto-extension is gone as of November 2025, a tourist eVisa is a fixed 30-day single entry, and the longer-stay route is the Business (Type E) eVisa you extend from inside Cambodia. Tourist eVisa $80 USD, Business eVisa $90 USD, both approved in 3 business days and delivered as a printable PDF by email, both with free resubmission if Immigration flags a correction, both backed by US-timezone support. If you are still unsure whether you even need a visa for your trip, our explainer on whether US citizens need a visa for Cambodia is the place to start.
