6 Translation Mistakes That Can Delay a USCIS Case

A small translation mistake can become a big problem in your file

You gather your documents, get them translated, and assume the hard part is over. Then a delay or a request for evidence arrives, and nobody explains why. Sometimes the cause is the translation. Here are six slips we see often. This is general information only: CPV is not a law firm and does not give legal advice.

1. Translating only "the important parts"

It is tempting to translate just the name, the date and little else. The federal regulation calls for a full English translation of any document with text in another language. A summary or partial translation can raise questions about the whole document, and that costs time. We take care of translating the complete document as it appears on the copy.

2. Forgetting stamps, backs of pages and margin notes

This is the one people miss most. A civil record with a margin note, a small stamp or text on the reverse is part of the document, and a full translation reflects it. A rushed translator often skips these because they "do not look important." We check every page, both sides, so nothing is left out.

3. Handing in a translation with no certification, or a half-finished one

This is where a common error hides. Under the regulation, the translator must certify two separate things: that the translation is complete and accurate, and that he or she is competent to translate from the source language into English. The Form I-485 instructions add a signature, printed name, date and contact details. If one piece is missing, the document may not meet what is asked. Our translations come with a signed certification; if your form asks for extra details, such as contact information, let us know when you order the translation.

4. Assuming that speaking both languages is enough

Speaking both languages is not the same as certifying a translation: the translator must state in writing that he or she is competent and that the translation is complete and accurate. The official pages we read do not say who may or may not translate, and we do not treat it as allowed or forbidden. If you are unsure about your case, ask USCIS or an attorney or accredited representative. If you would rather leave this work to a translator who certifies, that is what we do.

5. Sending a blurry copy to be translated

If the photo or scan is hard to read, no translation can faithfully reflect it. The instructions ask for legible photocopies. Before translating, we check with you that the copy reads completely and let you know if anything cannot be made out.

6. Paying extra for an "official stamp" nobody asked for

There is a common idea that a translation needs a special stamp. Neither the regulation nor the I-485 instructions we read mention one: they describe a statement signed by the translator. If a specific USCIS form or letter asks for something different, what that document says is what counts; for a particular case, ask USCIS or an attorney or accredited representative.
