Why Vietnamese is hard for basic OCR
Vietnamese uses the Latin alphabet with stacked marks. One vowel can carry a shape mark and a tone mark at once, as in ặ, ữ or ộ. A blurry scan or a basic OCR tool drops one of them, and the word changes. Ma, má, mà, mả, mã and mạ are six different words.
LoreAI reads the marks from scans and phone photos of typed and handwritten pages, translates the text and keeps every mark in names, so the English file spells people and places the way the original does.
How to translate a Vietnamese PDF to English with LoreAI
- Scan or photograph each page. Use even light and keep the page flat, so the small tone marks stay sharp.
- Type your email at the top of this page. The 6-digit code we send opens LoreAI. Your first document is free, up to 3 pages and 3 MB.
- Choose English. LoreAI detects Vietnamese on its own.
- Download the Word file. The form's fields come back as Word tables, label next to value.
Vietnamese names on US forms
Vietnamese names run family name first. In Nguyễn Văn An, Nguyễn is the family name, Văn the middle name and An the given name. On a US form, the family name field takes Nguyen and the given name field takes An, with Văn as the middle name, unless the person's passport or green card orders it differently. Follow that document.
Keep the marks in the translation even if US forms drop them, so the reader can match the translation to the original line by line.

Vietnamese dates run day first, as in ngày 05 tháng 03 năm 1985. In English that is March 5, 1985. Write the month in words so nobody reads 05/03 as May 3.
Vietnamese documents for USCIS
USCIS asks for a full English translation of any foreign language document, with the translator's certification that it is complete and accurate and that they are competent to translate from Vietnamese into English[1]. Viet Nam joined the Apostille Convention, which entered into force for it on September 11, 2026[2].
LoreAI is not a certified translation service. A person fluent in Vietnamese and English reviews the Word file and signs. The USCIS translation guide has the certification wording.
