How Do I Know If I Need Translations?

All documents submitted to immigration, which are not in English, must include complete translation into English. In addition, there must be a certification from the translator indicating that the translation is complete and accurate and attesting to his or her competence as a translator.

How Do I Know If I Need Original Documents?

Applications and Petitions must be submitted in the original.
The USCIS requires documentation to prove the existence of relationships and facts in support of petitions and applications. The following will clarify when originals are required and when photocopies may be submitted.
Submission of Supporting Documents - Original vs. Photocopy - If a supporting document is prepared by the issuing authority solely for the purpose of presentation to USCIS, an applicant or petitioner must submit the original document with the application or petition. Examples of supporting documents which must be presented in the original are:

•     Form I-20 issued by a Designated School Official to a foreign student
•     Form DS-2019 issued by a Program Officer to an Exchange Visitor
•     Labor Certification issued by the Department of Labor
•     Labor Condition Agreement with the Department of Labor endorsement
•     Form I-693 Medical Examination issued by a authorized civil surgeon
•     Vaccination Sign-off Supplement to Medical Examination Certificate
•     Attestations, formal consultations and advisory opinions (e.g., a letter from a recognized expert attesting to someone’s extraordinary professional skills)
•     Affidavits prepared in place of unavailable documents (e.g., an affidavit in place of a birth certificate where the official records were destroyed by fire)
•     Translations of documents (even when the rules allow submission of a photocopy of the document itself.)

NOTE: If the applicant or petitioner has already submitted the original document to the USCIS in connection with another matter, he or she may submit a photocopy along with an explanation of when and why the original was previously sent to the USCIS.

For all other documents, the applicant may submit a photocopy of the document required; however, he or she may be required to present the original:

in person, upon the request of a USCIS or consular official during an interview, or
by mail, in response to a written request from USCIS.

An original document submitted under these circumstances will be returned to the petitioner or applicant when no longer required.

How Do I Get Original Documents Back?

Original documents submitted when not required will remain a part of the record. If you decided at a later time that you want your original returned, please file Form G-884 with the office where you submitted the original document(s). The Form G-884 is available for those in the U.S. through Forms by Mail but is not available on the USCIS website.
