Signed statement of accuracy with the translator's name, credential number, and date.

In-place image translation

Why immigration law firms and applicants use Smartlink
Built for USCIS 8 CFR 103.2(b)(3)
U.S. immigration regulations require a "competent translator" certification for any non-English document. Every order ships with a signed Translator's Declaration that meets this requirement — not just a plain-text translation.
A 10,000+ term immigration glossary
Built specifically for EB-1A, EB-2 NIW, EB-5, O-1 and family-based filings, so award names, institution names, and job titles stay consistent across every document in your case.
Translation memory keeps names consistent
The same applicant name, institution, patent number, or publication title is translated the same way across recommendation letters, resumes, and certificates — one of the most common reasons cases get an RFE for translation issues.
Transparent, itemized pricing
Pricing is per character (not a vague "per page" estimate). The quote page lists every file with its character count and price before you pay — the quote is the final price, no add-on fees.

One transparent price includes the translation, translator's declaration, bilingual seal, and in-place image translation — the quote you see is the final price.
