We accept the following payment methods: WeChat Pay and Alipay. All prices are inclusive of applicable taxes. The exact quote is generated automatically by our system, based on the word/character count recognized via OCR from your uploaded file.

You agree to provide current, complete, and accurate information for all purchases made through this website.

4. Translation Delivery and Quality Assurance

Once translation is complete, the system will notify you by email to download the finished translation file. The estimated delivery time is provided at the time of order based on historical data. Because all translations are performed by professional translators, we cannot guarantee an exact timeline, but we make every effort to deliver within or ahead of the estimated time.

Service level commitment: every order on this platform is delivered in accordance with Section 4.3 "Full Post-Editing" of the ISO 18587:2017 standard — translation quality equivalent to human translation, suitable for publication and for formal legal, medical, and compliance purposes. All post-editing work is performed by translators who meet the ISO 18587 §6 competency requirements, with post-editing work records kept for audit purposes.

We commit to:

  • Accurate, professional translation content that meets USCIS filing requirements
  • Every translated document includes a Certificate of Translation Accuracy and translator qualification information
  • If you have concerns about translation quality, you may request a free revision within 24 months of order completion (for omissions/mistranslations/terminology errors/formatting non-compliance)
  • Our overall translation workflow follows the ISO 9001:2015 quality management system and the ISO 18587:2017 post-editing standard

5. Modifications and Revisions

You may submit a revision request via the order page within 24 months of order completion. The following three categories of issues are considered translation quality issues and are eligible for unlimited free revisions:

  • Minor errors (spelling errors, grammar errors, incorrect numbers/dates, missing paragraphs)
  • Accuracy issues (omissions, mistranslations, misunderstanding of the source text)
  • Formatting and compliance (not following the glossary, non-compliant layout, not meeting USCIS-Ready formatting standards)

The following may require an additional fee:

  • Changes to the content of the source file
  • New content beyond the scope of the original translation
  • Substantial rewrites based on subjective stylistic preference (that do not affect accuracy)

6. Intellectual Property
