Certified Chinese-to-English document translation starts at $19.99 per eligible page after scope confirmation. Standard 24-hour delivery applies to clear, complete, ordinary modern typed files with a known writing system, page count, condition, name treatment, and recipient scope. Each completed translation includes a signed certificate of accuracy.
Corpus reviews Simplified Chinese, Traditional Chinese, bilingual Chinese/English records, and mixed written packets. Simplified and Traditional describe written character forms; Mandarin and Cantonese describe spoken varieties and related writing practices. The characters, issuer text, seals, dates, and complete supplied image—not a filename, surname, address, flag, or assumption—control how a file is scoped.
Use checkout only for an eligible clear, complete, ordinary modern typed file with a known page count. Select the applicable named option, Chinese (Simplified) or Chinese (Traditional), only when the source writing system is clear.
Request quote review for mixed or uncertain writing, Cantonese-specific or dialect-dependent content, handwriting, historic type, damaged scans, dense tables, unclear page order, inconsistent identity spelling, or recipient-controlled wording. The quote form lists Chinese (Simplified), Chinese (Traditional), and Mandarin; add Cantonese or other language context in the notes field.

Other supplied written records may include divorce records and court judgments, passport biographical pages, police records, professional qualifications, school diplomas, academic verification reports, business licenses, company records, powers of attorney, declarations, contracts, tax or financial records, technical records, vaccination records, medical examinations, and hospital discharge summaries. Relevant category guidance is available for academic records, legal records, business records, and medical records.
Is the source Simplified Chinese, Traditional Chinese, both, or mixed with English?
Readable characters, labels, issuer text, stamps, dates, and every page establish the writing present in a supplied file.
Simplified and Traditional Chinese are written character forms, not spoken dialects and not different USCIS standards. Mandarin and Cantonese are spoken varieties with related written practices. Shared characters, regional forms, English, numbers, or another language may appear in the same packet, and geography does not prove which form appears on every page.
Review starts from the complete image. A Mainland China, Taiwan, Hong Kong, Macau, or Singapore issuer provides context, but it does not establish language, identity, nationality, authenticity, or recipient sufficiency. Genuine layers remain separate and traceable. Mixed or uncertain material requires quote review rather than silent classification.
The broad owner covers written Chinese document translation. Use the distinct Mandarin and hukou service for Mandarin-specific or PRC household-register support, and the separate Cantonese service for Cantonese-specific written content. Neither spoke becomes a duplicate broad owner.
How are character forms, variant glyphs, punctuation, and OCR controlled?
Every readable character, regional form, punctuation mark, number, and field relationship is checked against the supplied image.
The translation follows the characters actually printed. Simplified forms are not silently converted to Traditional, Traditional forms are not silently converted to Simplified, and a regional variant is not normalized because another form looks more familiar. Vertical and horizontal reading order, repeated headings, names, numbers, punctuation, and table relationships are checked in context.
OCR is supporting evidence only. It may split or merge characters, substitute a familiar glyph, lose punctuation, or rebuild faint text from an expected template. Review compares extracted text with the source at usable zoom. A genuinely inconsistent repetition remains visible or is raised for review. Faint or unreadable text is marked [ILLEGIBLE]; no character, name, date, number, or mark is invented.
How are Chinese names and Latin-script spellings handled?
Printed characters, name order, and every supplied Latin-script form stay traceable to their source fields.
Pinyin is a recognized romanization framework, but a passport, older record, Taiwan or Hong Kong document, family usage, or recipient file may show another established spelling. A customer or recipient spelling can guide treatment only when evidence links it to the same identity and the instruction is documented.
Review does not infer identity, reverse a name, anglicize it, assign nationality or gender, or silently replace a source spelling. Characters and Latin forms are preserved as printed, including genuine differences among fields. Conflicting or unclear versions require quote review. A translation records source evidence; it does not decide that two people are the same or that one spelling is legally controlling.
Which PRC civil and notarial records require complete-packet review?
A PRC civil or notarial packet is scoped by its readable issuer, date, title, pages, seals, endorsements, attachments, and reverse sides.
PRC materials may include a notarial certificate or booklet (公证书, Gong Zheng Shu), a resident household register (居民户口簿 or 户口本), a medical certificate of birth, an identity card, a police record, or another civil record. The U.S. Department of State China schedule supplies issuer and document context, not proof that a customer's record is authentic, available, complete, or acceptable to a recipient.
Every supplied cover, certificate page, attached record, person entry, amendment, stamp, seal, endorsement, and reverse side must remain in page order. Red seals or chops are described from readable appearance; Corpus does not authenticate them or claim they carry a particular legal effect. A household register is not presented as a substitute for a birth certificate or as proof of relationship. Recipient instructions determine required evidence.
How are Taiwan household, civil, and education records handled?
Readable Taiwan records keep their Traditional-character fields, issuer wording, entries, amendments, names, seals, and dates tied to the source.
A household registration transcript may use wording such as 戶籍謄本. The printed title, issuer, people, entries, amendments, dates, seals, and every relevant page control the translation. No familiar form is used to fill a blank, cropped, or damaged field.
Where a Republic of China calendar date appears, the printed form is preserved. Any converted date must be explicit, source-supported, and consistent with documented recipient instructions; it is never substituted silently or generalized to every Taiwan record. Translation does not establish identity, family relationship, authenticity, legal effect, credential equivalency, or recipient acceptance.
How are Hong Kong, Macau, Singapore, and bilingual records handled?
Each readable Chinese, English, Portuguese, Malay, or other language layer stays connected to its own heading, field, and page position.
Bilingual headings and English already printed on a record are retained as source content rather than discarded. Parallel language fields may not align word for word. Review preserves issuer wording, IDs, tables, annotations, seals, and genuine differences without using one layer to reconstruct unclear text in another.
Hong Kong, Macau, or Singapore as a place of issue does not establish spoken variety or prove that every page uses one writing system. Cantonese-specific, dialect-dependent, mixed-script, handwritten, historic, or uncertain wording requires quote review. The distinct Cantonese spoke remains available for that purpose without cannibalizing this broad written-document owner.
How are seals, handwriting, dense tables, scans, and page order reviewed?
Every front, back, margin, fold, attachment, photograph, seal, stamp, signature, QR panel, serial number, and table must be visible for review.
Uncropped color scans or photos at usable resolution provide the best basis for character-level review. Blur, glare, compression, clipping, embossing, overlapping marks, handwriting, historic type, dense transcripts, mixed languages, missing pages, or unclear sequence can change price, timing, and scope. These files require a clearer image or quote review.
OCR never replaces the image. Page order and field relationships are preserved, and truly unreadable source text is identified as [ILLEGIBLE]. Corpus does not reconstruct expected content, authenticate a seal, verify a QR code or registry, retrieve a record, evaluate credentials, or decide the legal effect of a supplied document.
What does the recipient require, and should the buyer order or quote?
Recipient instructions control the submission packet; checkout fits eligible clear files, while uncertain or recipient-sensitive work needs a quote.
For USCIS, 8 CFR 103.2(b)(3) requires a full English translation certified as complete and accurate, plus certification that the translator is competent to translate. The rule does not create an acceptance or case-outcome guarantee. NVC or consular posts, courts, schools, credential evaluators, licensing bodies, employers, and foreign authorities control their current document and format requirements.

Frequently asked questions
What do USCIS translation requirements say for Chinese documents?
A foreign-language document submitted to USCIS must include a full English translation and a certification that the translation is complete and accurate and that the translator is competent to translate. Corpus provides certified written-document translation; the rule does not support an acceptance or case-outcome guarantee.
What is the difference between Simplified and Traditional Chinese for USCIS?
Simplified and Traditional describe written character forms, not different USCIS standards or proof of origin. The translation must follow the characters and language actually shown in the complete source; mixed or uncertain files need quote review.
Do you translate Chinese birth certificates (出生证明) for USCIS?
Readable Chinese birth records can be translated when every page, reverse side, seal, stamp, annotation, and attachment is supplied. Document title and format vary by issuer, date, and jurisdiction, so the source image and recipient instructions control scope.
Can you translate a Chinese 户口本 (household registration)?
A readable PRC household-registration book can be reviewed as a complete supplied packet. Relevant covers, household pages, person entries, amendments, stamps, and reverse sides must be included; translation does not establish relationship, authenticity, or recipient sufficiency.
How long does certified Chinese translation take?
Standard 24-hour delivery applies after scope confirmation only to eligible clear, complete, ordinary modern typed files with known writing system, page count, condition, name treatment, and recipient scope. Complex packets require quote review.
Can I translate my own Chinese documents for USCIS?
The controlling rule requires a full English translation and a certification of completeness, accuracy, and translator competence. It does not create a blanket professional-translator requirement; buyers should follow current recipient instructions. Corpus provides an independent certified translation service.
Do you translate Taiwanese household registration (戶籍謄本) for USCIS?
A readable Taiwan household registration transcript can be reviewed when all relevant pages, entries, amendments, seals, names, and dates are supplied. The translation preserves the source and does not promise that a recipient will accept a particular record or format.
What Chinese documents are needed for a USCIS I-130 petition?
Required evidence depends on the filing and current USCIS instructions. Any submitted non-English document must follow the full-translation and certification rule. Corpus translates supplied written records but does not select evidence, provide legal advice, or guarantee an outcome.
