In order to make an informed decision, the Entry Clearance Officer normally needs to see original documents. But as applications are transferred from Phnom Penh to Bangkok, it could be inconvenient if applicants are without original documents for any period of time. By bringing copies with the originals to Phnom Penh, the Entry Clearance Assistant can verify that the documents are the same as the original and confirm this to the Entry Clearance Officer. Original documents can be returned immediately to the applicant.

In order to make an informed decision on an application, documents need to be translated into English to aid the process.
