FILLVISA OS MAY FIT WHEN
DS160.IO MAY FIT WHEN

A self-hosted form tool does not automatically recreate those business services.
SELF-HOSTABLE. AGPL-3.0 LICENSED.

Choose a repository release, review its included forms and documentation, and keep a record of the version you deploy.
View the repository →02 / HOST YOUR COPY
Use a static web server and test the form workflow, asset loading, downloads, and saved progress. Your deployment remains your responsibility.
Read setup documentation →03 / UNDERSTAND THE LICENSE
Review the license before adapting, distributing, or operating a modified version for others. The repository’s license text is the authoritative reference.
Read the license →BEFORE YOU CHANGE TOOLS
Try Fillvisa OS on a sample before moving work in progress. Confirm form coverage, CEAC interactions, and how you will preserve progress.
Identify the documents and outputs you plan to prepare. Separate software needs from filing guidance, customer support, and professional help you may want.
Use the directory and repository to verify each supported form. Test the actual output with fictional data, including repeated fields or extra sections.
If you have started with ds160.io, confirm how to retain your answers and documents. There is no promised one-click import into Fillvisa OS.
Local browser progress does not automatically follow you to another device. Check export and backup options, keep your documents organized, and decide who will review the completed work.
Before changing a paid service or business workspace, review its terms and the assistance you would lose. Verify your alternative process end to end and follow the relevant official filing instructions.
