“Certified” and “notarized” are often treated as synonyms online, but they describe different things.
What USCIS requires
For foreign-language evidence, the federal rule requires:
The regulation does not add a universal notary requirement to that list.
What notarization actually does
A notary generally authenticates a signature or identity according to the rules of the jurisdiction where the notarization is performed.
That is not the same as certifying translation quality.
A notary normally does not compare every translated sentence with the source language simply because a signature is notarized.
Why do some people still ask for notarization?
Because USCIS is not the only possible receiving authority.
A court, university, embassy, state agency, private institution or attorney may ask for another formality in a particular context.
The correct question is therefore:
> What does the actual receiving authority require for this document?
For an ordinary USCIS translation requirement, translator certification is the central rule. For another use, check that institution's instructions.
Certified translation vs notarized translation
| Term | Main function | |---|---| | Certified translation | Translator attests to completeness/accuracy and competence | | Notarized signature | Notary verifies/signs according to applicable notarial procedure | | Sworn translation in Brazil | Official translation regime performed by a qualified public translator under Brazilian rules |
These categories should not be mixed simply because they all sound “official.”
Should I order notarization anyway?
Do not add a formality automatically just because it sounds safer.
Instead:
That avoids paying for a step that may not be relevant while still allowing additional formalities when genuinely required.

Frequently asked questions
Direct answers about this topic
Is a notarized translation stronger for USCIS?
Notarization does not replace the translator certification required by the federal translation rule.
Does a Certificate of Translation Accuracy need a notary?
The general USCIS translation regulation does not impose a blanket notarization requirement. Follow any additional filing-specific instruction or attorney request.
Is sworn translation the same as notarized translation?
No. A Brazilian sworn translation is an official translation regime; notarization concerns a notarial act. They are different concepts.
What should I tell F2 before ordering?
Tell F2 the receiving authority, document type, source language and any attorney or institution instruction requiring a special format.
