The certified translation must be attached to the source document in the original language. The source document should, if possible, be an original document with a handwritten signature and stamp imprint. If you want to keep your original separate, please provide me with a copy certified by a notary to be attached to the translation. If you do not have such an original, I can attach a normal print-out of your source document to the translation, but you must check with the accepting authority whether they accept it.
