Please do not submit your only original transcript or degree certificate to Portland State. The original is your only copy of your academic work and you do not want it to be lost. Instead, send a photocopy of the original document to the issuing institution and request that they attest the copy. They will validate the copy according to their records, seal it in an intitutional envelope and give it to you or send it directly to Portland State as an official transcript or degree certificate. All official documents submitted to Portland State become the property of the University and cannot be returned.
Additionally, please do not send your only original transcript or degree certificate to a translation service. Find out from the service what type of documentation they need for translation purposes.
