H-1B Cap Season 2026: Which Documents Need Certified Translation?

H-1B cap season is in full swing. With the April 1, 2026 registration window now open, employers and foreign workers are assembling petition packages under tight deadlines. One part of the process that often gets overlooked until the last minute is certified translation — specifically, which documents in an H-1B package require certified English translations for USCIS.

This guide covers the most common documents that need translation, what USCIS actually requires, and how to plan around the April filing deadline.

Why USCIS Requires Certified Translation

The requirement is found in 8 C.F.R. § 103.2(b)(3): every foreign-language document submitted to USCIS must be accompanied by a full English translation that the translator certifies as complete and accurate, along with a statement that the translator is competent to translate from the source language into English.

There are no exceptions for "obvious" documents, for documents from certain countries, or for cases where the USCIS adjudicator might know the language. If it's in a foreign language, it needs a certified English translation.

Foreign Diplomas and Degree Certificates

This is the most common document requiring translation in an H-1B petition. H-1B specialty occupation status requires that the beneficiary hold a U.S. bachelor's degree or equivalent in a field directly related to the job. For foreign nationals who earned their degrees abroad, the diploma — typically issued in the language of the country — must be translated.

The diploma translation should capture everything on the face of the document: the institution name, degree title, recipient name, date of conferral, official signatures, and any stamps or seals. Omitting stamps or seals is one of the most common causes of Requests for Evidence (RFEs).

Foreign Academic Transcripts

Alongside the diploma, USCIS and credential evaluators typically require official transcripts to document the coursework behind the degree. If those transcripts are in Portuguese or Spanish, they must be fully translated, page by page, including course names, credit hours, and grade notations.

If you are using a credential evaluation service to establish U.S. degree equivalency, note that many evaluators require certified translations of the underlying foreign documents before they can perform the evaluation. Build this into your timeline.

Foreign Employment Records

Some H-1B petitions — particularly for positions where a U.S. degree equivalent is established through a combination of education and progressive work experience — require employment verification letters or records from prior foreign employers. If those letters were issued in a language other than English, they need certified translation.

Typical documents in this category include employment verification letters on company letterhead (confirming job title, duties, and dates of employment), HR records, and professional reference letters written in a foreign language.

Birth Certificates and Family Documents for H-4 Dependents

If the H-1B beneficiary has a spouse or children who will be filing for H-4 dependent visas concurrently, their documents require separate certified translations. The most common H-4 documents that need translation include:

• Birth certificates — For each dependent child
• Marriage certificate — For the spouse filing for H-4 status
• Prior divorce decrees — If either spouse was previously married

H-4 filings are often done concurrently with the H-1B petition to minimize immigration limbo for the family. That means the H-4 translations need to be ready at the same time as the H-1B translations — not as an afterthought.

Foreign Professional Licenses and Certifications

For H-1B petitions in regulated fields — physicians, engineers, architects, nurses, certain IT roles — the petition may include professional licenses or certifications issued by foreign governments or professional bodies. These must be translated if they are in a foreign language, including the issuing authority's identifying information and any registration or license numbers.

Planning for the April 1 Filing Window

The H-1B cap lottery registration opened in March, and selected petitioners must file full petitions beginning April 1. For many employers, that means an extremely compressed timeline between lottery selection and petition assembly. Translation should not be the bottleneck.

Standard certified translation of a diploma or transcript commonly takes a few business days, depending on document length, legibility, and current queue. Rush processing should be reserved for genuine emergencies — rushed work increases the risk of minor errors that can draw scrutiny.

If your beneficiary's documents include Spanish, Spanish-to-English certified translation is one of the most commonly ordered services during H-1B season. For Portuguese credentials, Portuguese-to-English certified translation may be needed for both the diploma and transcripts.

Summary

For H-1B petitions, the foreign-language documents most commonly requiring certified translation are: foreign university diplomas, academic transcripts, prior employment records from foreign employers, professional licenses, and (for H-4 concurrent filings) birth certificates and marriage certificates. Start translation early — well before April 1 — to give your attorney time to review the completed package before filing.
