My person to be sponsored needs to get some papers translated (marriage cert and other things like this - I will need to get my paystubs translated I think too) - Now, in Korea, just WHO can translate these papers?
Most lawyer's offices have a translator either in their office or one that they use that is nearby. Find a lawyer's office. If you can't find one just go down to the local court house and look around the surrounding area. There will be plenty of them nearby who can translate/notarize for you.
Korean translators are not licensed or certified. They just do the translation, swear an affidavit as to the accuracy of their translation and CIC will accept it.
