The Cambodian government application portal specifies a processing time of 4 business days.
In our experience, applications take between 2 and 4 business days, sometimes longer depending on how busy the Cambodia Immigration office is.
As always, you'll receive your eVisa as soon as it's approved and we will immediately contact you if we encounter any issues.
Please note that the Cambodian government only allows the eVisa to process 90 days before your travel date.
