Exactly - what they mean, I assume, is a certified translator translation, because this passage is clearly about the fact that you can't translate the documents yourself, and notaries are lawyers, not translators! I assume it is possible to get a document translated by a regular translator and then have a notary notarize the translation, but I don't think it's the translation, that needs to get notarized. certified translators are translators with governmental qualifications to certify that the translation is the same as the original, and typically they attach a copy of the original with their translations - according to these instructions, you're supposed to attach the original with the translations from a certified translator. And if you don't have originals, but copies of documents, you need a lawyer, a notary,to notarize them, and then translate them by a certified translator. This is exactly what ScottishPolish said, and did, and they got approved. And this is also what Sous is saying: "Again anytime you make a copy of a required document the copy must be notarized. Then the translation is certified." - a *copy* - so if you go and photocopy your birth certificate or something, then the photocopy needs to be notarized. But not the original, and the translation itself is of the document provided, be it copy or original, that you attach as well; if it's a copy then it needs a notary stamp.
Is that what everyone did?
I think the confusion here is the understanding of what the translation is - the translation is just a translation, of the original document (unless it's a copy, which needs to be notarized), and with it they require the original document (and not the photocopy of the document which the translator attaches to the translation - this is standard procedure). but there is no need, or way to notarize a translation - it's already notarized (i.e. it's truthfulness to the original is officially confirmed) by the translator.
I'd appreciate if you let me know what you had your friends/family write in your letters, too
