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.
