Cambodia Visa for American Students: The ES Extension Path
There is no online "student visa" for Cambodia. American students enter on the standard eVisa — $80 USD Tourist or $90 USD Business — then convert to the ES (student) extension in-country once they have an enrollment letter. Here is the full path for 2026.
What visa does an American student need to study in Cambodia?
Cambodia does not issue a separate online "student visa." As a US citizen, you apply for the standard eVisa before you fly — the Business eVisa ($90 USD all-in, approved in 3 business days) is the right class for almost every study stay, because it is the only Cambodia visa that can be extended in-country. After you arrive and have an enrollment or acceptance letter from your university, language school, or exchange program, you convert to the ES (student) extension through a Cambodian immigration agent. ES extensions run 1, 3, 6, or 12 months and are renewable, so you can cover a full academic year. The Tourist eVisa is a 30-day dead end for students — its auto-extension ended in November 2025 — so do not enter on it if you plan to study.

- There is no separate online "student visa" for Cambodia. American students apply for the standard eVisa first, then convert to the ES (student) extension after arrival.
- For a study stay you almost always want the Business eVisa ($90 USD all-in, 3 business days), not the Tourist eVisa — only the Business class can be extended in-country, and study stays run well past the 30-day Tourist cap.
- The ES extension is the student sub-type of the in-country extension, lodged through a Cambodian immigration agent once you have an enrollment or acceptance letter from your school. Lengths run 1, 3, 6, and 12 months, renewable.
- The Tourist eVisa auto-extension ended in November 2025, so a Tourist eVisa is now a hard 30-day dead end for anyone planning to study — there is no path to stay longer on it.
- The Cambodia e-Arrival Card is still separate and mandatory for every air arrival: 14 fields, $5 USD verified through us, submitted within 7 days before you fly.

Mapping common American student trips to the right path
- Short language intensive or field study under 30 days — e.g. a two-week Khmer-language course or a one-week academic field trip. The Tourist eVisa ($80 USD) covers it, since you leave before any extension is needed. No ES conversion required.
- Semester abroad, roughly 3 to 5 months — e.g. a Boston student on a fall-semester placement at a Phnom Penh university. Enter on the Business eVisa, then convert to a 3-month or 6-month ES extension. The 6-month block usually covers a full semester plus exam period with room to spare.
- Full academic year, language immersion year, or gap year — e.g. a recent US graduate doing a year of Khmer study in Siem Reap. Enter on the Business eVisa, then take a 12-month ES extension. It is multi-entry, so you can fly home for the holidays and return.
- Multi-year degree at a Cambodian university — e.g. an American enrolled in a full bachelor's or master's program in Phnom Penh. Enter on the Business eVisa, then renew the ES extension year by year. Most degree students settle into renewing 12-month ES blocks annually.
- Research fellowship or exchange with mixed study and unpaid work — e.g. a US doctoral researcher affiliated with a Cambodian institution for eight months. Business eVisa entry, then a 6-month or 12-month extension; whether it is filed as ES or EB depends on what your host institution documents.
سوالات متداول
Is there a Cambodia student visa I can apply for online before I fly?
No. Cambodia does not issue a separate online student visa. As a US citizen you apply for the standard eVisa first — the Business eVisa ($90 USD all-in, 3 business days) for any study stay over 30 days — then convert to the ES (student) extension in-country once you have an enrollment or acceptance letter from your school. The student status is built on top of the eVisa after arrival, not granted from the United States beforehand.
Should an American student enter on the Tourist or Business eVisa?
The Business eVisa ($90 USD), for almost every study stay. Only the Business eVisa (Type-E) can be extended in-country, and only it can convert to the ES student extension. The Tourist eVisa ($80 USD) caps at 30 days with no path to extend — its auto-extension ended in November 2025 — so it is a dead end for students. The only exception is a short program that genuinely wraps inside 30 days, where the Tourist eVisa is fine.
What is the ES extension in Cambodia?
ES is the student sub-type of Cambodia's in-country extension of stay. After you arrive on the Business eVisa, a Cambodian immigration agent lodges the ES extension on your behalf, using your enrollment or acceptance letter as proof of study. ES extensions are available in 1, 3, 6, and 12-month blocks, and they are renewable, so you can cover a full semester, a language year, or a multi-year degree by stacking them.
What documents do I need for the ES student extension?
Beyond the standard extension paperwork your agent handles, the key student-specific document is an enrollment or acceptance letter from your Cambodian university, language school, or program, on the institution's letterhead. You will also need your passport (the agent holds it while processing) and your existing Business eVisa entry. The enrollment letter is the piece most likely to cause delays, so request it from your program's international-student office before you fly.
How long can I study in Cambodia on the ES extension?
As long as you keep renewing it. ES extensions come in 1, 3, 6, and 12-month lengths and are renewable, so a full academic year usually runs on a 12-month ES block, and a multi-year degree runs on annual renewals. The 12-month ES extension is multi-entry, which lets you fly home to the US for breaks or travel to Bangkok or Singapore and return without losing your status.
