Both the Cambodia Tourist eVisa and Business eVisa are single-entry for US citizens — one arrival per visa. Here is exactly what that means for re-entry, what happens the moment you leave, and how Americans planning a Vietnam or Thailand loop should sequence a second visa.

The Cambodia eVisa for US citizens is single-entry only. Both the Tourist eVisa ($80 USD all-in) and the Business eVisa ($90 USD all-in) give you exactly one arrival into Cambodia. The visa is valid for 3 months from issue and lets you stay up to 30 days on that single entry, but the moment you exit the country the visa is finished — even with days left on your stay. There is no multiple-entry option on the standard Cambodia eVisa. If you plan to leave and come back — for example, a side trip to Vietnam or back into Thailand — you simply apply for a second eVisa before you re-enter, at the same price and the same 3-business-day approval.
This guide breaks down exactly what single-entry means in practice, when an American genuinely needs a second visa, how the 3-month validity differs from the 30-day stay, and how to sequence a regional loop so you are never stuck at a gate. If you are still deciding between the two visa products, our Tourist vs Business eVisa comparison covers which one fits your trip — but on the single-entry question, they behave identically.
This is also why the all-7 Thailand-Cambodia land borders being closed since June 2025 matters less for re-entry planning than you might think: even when those crossings reopen, hopping out and back would still burn your single entry each way. The shape of the visa, not the border status, is what governs re-entry. Our guide on how long US citizens can stay in Cambodia walks through the stay clock in detail if that is the part you are weighing.

The good news is that a second Cambodia eVisa is the same simple process as the first — same $80 USD for Tourist or $90 USD for Business, the same 3-business-day approval, delivered as a printable PDF by email. There is no penalty, no cooling-off period, and no limit on how many single-entry eVisas you can hold across separate trips. If you frequently re-enter and are weighing whether a longer in-country path fits better, our explainer on whether you can still extend a Cambodia tourist visa covers the post-November-2025 rules.
For an extended stay rather than a genuine loop, the calculus changes — a single Business eVisa with an in-country extension can be cleaner than repeatedly leaving and re-entering on fresh single-entry visas. The Business eVisa is the only Cambodia visa that supports in-country extensions, which is why long-stay Americans gravitate to it. Our breakdown of the ordinary E-class visa explains the EB, EG, ER, and ES extension tracks if a longer stay is on the table.
The bottom line for Americans: the Cambodia eVisa is single-entry, full stop — Tourist or Business, the rule is identical. One arrival per visa, 3 months to use it, 30 days of stay once you are in. Plan a second eVisa and a second e-Arrival Card for any trip that leaves and returns, and you will never meet the single-entry rule as an obstacle. If you are still mapping which visa your trip needs in the first place, our which Cambodia visa do I need guide is the place to start.
