You will receive the translation by email AND USPS priority mail.

After we email you the completed and certified translation, including the Certificate of Accuracy, the translation packet will be mailed to your address by USPS priority service.

You will also get a tracking number when you receive the translation by email.

You may not need the hard copy* to file your translation with USCIS or the court system, since they usually just want a copy and not the original initially. You will, however, need the original certificate of accuracy for your interview with the immigration officer.
