No translator certification required. This translation is for my own purposes. Usually a text or Word document.
For institutions which require the translator's signature on the document. You will receive an electronic PDF copy only. Print it at home as many times as you need — and, yes, this is exactly what you need for USCIS!
Only necessary if you have been specifically asked to have the translation notarized, or you want a paper copy mailed to you. It is the same as a certified translation, but the translator signs in front of a California notary public. Allow extra time for shipping.
