The job websites of some US universities ask to upload a doctoral certificate for assistant professor positions in Computer Science. My doctoral certificate is not in English. IMHO, a quick look on it suffices to read my name and "doktor rerum naturalium" to convince oneself that I indeed have a PhD. Still, no website mentions that a certificate should be in English. As a rule of thumb, without asking, should I
continue uploading my current foreign-language certificate, or
get my certificate translated by a sworn translator, or
self-translate my certificate?
