Do I need to apply two visas within such a short period of time?

No, you do not need to apply for two Cambodian visas within a short period of time. Only one visa should be adequate for your entire visit, with a maximum stay of 30 days and a single entry.

If you are planning to enter Cambodia multiple times within a short period, so, sure, you will need to apply for a new visa each time you enter the country. Each Cambodian e-Visa is only good for one entrance.

Key Points Regarding The Cambodia Visa Rules

Single Entry Visa

A Cambodia tourist visa (Visa T) allows single entry. It means it becomes invalid once you leave the country. Therefore, if you exit Cambodia, you cannot use the same visa to re-enter. Instead, a new visa application is required for your return.

Cambodia single entry visa can be applied for through the e-Visa system or obtained upon arrival at designated entry points in Cambodia. Each application will require the necessary documentation and payment of the visa fee.

Multiple Entries Visa

If you are planning to enter and exit Cambodia frequently, consider applying for a Business Visa (Type E), which can be issued as a multiple-entry visa and allows for longer stays and extensions.

Applying for a new Cambodia visa E with multiple entries may take some time, especially if done through an embassy or consulate rather than online. So, ensure that you plan your travel itinerary accordingly.

In summary, yes, you will need to apply for a new Cambodia e-visa each time you enter the country after leaving, as the Tourist Visa does not allow for multiple entries.
