Show HN: I made a free alternative to SimpleCitizen (YC S16)

https://fillvisa.com/
1•junaid_97•1h ago
I'm building Fillvisa - It's a free USCIS form-filling web-app

USCIS forms still use XFA PDFs, which don’t let you edit in most browsers. Even with Adobe, some fields break and are unfillable.

So I converted the PDF form into modern, browser-friendly web forms - and kept every field 1:1 with the original. You fill the form, submit it, and get the official USCIS PDF filled.

I found out SimpleCitizen(YC S16) offers a DIY plan for $529 [1]

---

What Fillvisa does:

- Fills USCIS forms with a guided web interface. - Autosaves as you go - Generates a completed PDF ready to print and mail - Works offline after first load

What it doesn't do:

- It won't file for you. - No lawyer review. If your case is complex, hire an attorney.

---

How do I maintain the forms + business model:

Fillvisa will always be 100% free for immigrants. I'm building a paid version (plus.fillvisa.com) for immigration professionals (lawyers, paralegals, document prep specialists).

Both the apps utilize the same form + mapping. Thus,it takes care of revenue + I have incentive to maintain the forms.

---

I shared the prototype on FB groups and Reddit - most DIY applicants love it :)
