USCIS requires a full English translation of a foreign-language document submitted, certified complete and accurate by a translator competent to translate into English. A summary should not be presented as that full translation.
Preserve what the underlying document says
Keep the original and corresponding translation together. A concise explanation may help organize the case but does not replace the required translation of the submitted evidence. Two documents are doing different jobs, and only one of them satisfies the requirement.
The full translation renders the submitted document in its entirety, and it travels with a certification that the translation is complete and accurate and that the translator is competent to translate from French into English. The covering explanation is an advocacy document: it tells the reader what to look at, in what order, and why a particular clause matters. Hypothetical example: a French notarial statement runs to eleven pages, and a two-page English précis is submitted with the original attached on the reasoning that the précis captures everything important.
The reader has no way to test that judgment, and the requirement has not been met. Produce both, keep them physically distinct, and never let the explanation borrow the translator's certification. Note also that a faultless translation says nothing about whether the underlying capital was lawfully sourced, genuinely placed at risk, or applied to an enterprise that will create the required jobs.
