The short answer is no: a Cambodia Tourist eVisa cannot be converted to a Business eVisa once you are in the country. The class is locked at application. Here is exactly why, the only real fix if you guessed wrong, and how to pick the right class before you fly.

No. Cambodia does not allow you to convert a Tourist eVisa (Type-T) into a Business eVisa (Type-E) once you are inside the country. The visa class is fixed at the moment you apply, and the eVisa system has no in-country switch path for US citizens. The Tourist eVisa caps at a single 30-day stay with no extension, so if you entered on it and now need business activities or a longer stay, your only clean option is to leave Cambodia and re-enter on a fresh Business eVisa ($90 USD all-in, approved in 3 business days). The far cheaper move is to choose the correct class before you fly — if there is any chance your trip involves work, meetings, or more than 30 days, apply for the Business eVisa from the start.
