USCIS forms are painful. The official PDFs are XFA-based - broken in most browsers. Third-party tools charge money or require an account just to get started.

Fillvisa is different: it runs entirely in your browser, saves your progress to localStorage, and generates a real fillable AcroForm PDF - ready to print and submit. No account. No server. Your data never leaves your device.

If you or someone you know is navigating the immigration process, I'd love for you to try it and tell me what's missing.

Features:

Auto-save: Your progress is saved automatically, allowing you to pause and resume without losing any data.

Local-only Storage: All information is stored on your device, ensuring complete privacy and security.

Automatic Form Filling: Fillvisa provides perfectly formatted, ready-to-download USCIS PDFs without the need for manual edits or additional tools.

Built-in Signature Pad: Sign forms directly in your browser, eliminating the need for printing or scanning.

Smart Form Checks: Built-in validation ensures that mistakes are caught instantly, streamlining the form completion process.

Fillvisa is designed to make immigration form preparation accessible and stress-free, allowing users to focus on their new life rather than paperwork.

Whether you're applying for a visa, renewing a green card, or changing your address, Fillvisa simplifies the process with its user-friendly interface and comprehensive features.

Analysis of Filllvisa

Overall verdict

  • I don't have verified, up-to-date information about Fillvisa (fillvisa.com), so I can't confirm whether it is a good or reputable service. Visa-related and immigration-assistance websites vary widely in legitimacy and quality, so it's important to verify independently before using or paying for such a service.

Why this product is good

  • I do not have reliable or current data on this specific website's reputation, ownership, or user reviews.
  • Visa-assistance services can range from legitimate document-preparation help to scams, so claims should not be taken at face value without verification.
  • No independent, verifiable reviews or regulatory information about Fillvisa were available to assess its credibility.

Recommended for

  • Not recommended to rely solely on this responseโ€”users should independently verify the company's legitimacy through official government visa resources, consumer review sites (like Trustpilot or BBB), and check for verifiable contact information, business registration, and user testimonials before using the service.
  • Individuals seeking visa help should generally prioritize official embassy/consulate websites or licensed immigration attorneys over third-party services with unverified track records.

Questions & Answers

As answered by people managing RootData and Filllvisa.

What's the story behind your product?

Filllvisa's answer:

Built by Junaid, a founder with a personal connection to the immigration experience. The core frustration was that existing free tools were either low-quality fillable PDFs, server-side tools that harvested user data, or paywalled SaaS products. Fillvisa was built to give immigrants the tool they actually deserve - professional-grade, private, and genuinely free.

How would you describe the primary audience of your product?

Filllvisa's answer:

Immigrants navigating the U.S. naturalization or adjustment-of-status process on their own - people filing forms like the N-400 without legal representation, often cost-sensitive, frequently non-native English speakers, and deeply privacy-conscious about where their personal information goes.

Why should a person choose your product over its competitors?

Filllvisa's answer:

It's free with zero friction - no signup, no paywall, no upsell nag. Your data stays on your device. The output is a properly filled, submission-ready PDF, not a printable web form. For immigrants who can't afford an attorney and don't trust third-party servers with sensitive personal data, that combination is hard to beat.

What makes your product unique?

Filllvisa's answer:

Fillvisa is 100% client-side - no account, no server, no data ever leaves the browser. It runs entirely on localStorage, generates real AcroForm PDFs via pdf-lib, and embeds structured JSON metadata directly into the PDF so forms can be re-imported and resumed later.

No other free USCIS form tool offers that round-trip fidelity.

Which are the primary technologies used for building your product?

Filllvisa's answer:

HTML, vanilla JavaScript, pdf-lib (PDF generation), localStorage (persistence), and a per-page -map.js validation config architecture. No frameworks, no backend, no database. Fully static and deployable as a CDN asset.

Who are some of the biggest customers of your product?

Filllvisa's answer:

As a free consumer tool, Fillvisa doesn't have "customers" in the traditional sense. It has users - immigrants filing USCIS forms independently. There are no named enterprise accounts or notable client logos to list.

  • Ask HN: What Are You Working On? (May 2026)
    Fillvisa โ€“ https://fillvisa.com USCIS immigration forms are still distributed as XFA PDFs - a deprecated Adobe format that modern browsers and PDF readers can't render or fill. Immigrants download them, get a blank white page, and give up. I built a client-side tool that converts those XFA forms into fillable web forms - no account, no upload, everything runs in the browser. That's the free tier.
