Frequently asked questions about Fillvisa alternatives
A closer look at cost, capabilities, and choosing the right workflow.
Yes. Fillvisa OS offers free, browser-based immigration form preparation with public source code. You can inspect, customize, and self-host it under the AGPL-3.0 license. Government filing fees and any self-hosting costs are separate.
Fillvisa OS focuses on preparing supported immigration forms. It is not a complete replacement for a firm’s case management system. Before switching, assess your needs for client intake, billing, case tracking, document management, and team collaboration.
Start with the forms and workflows you need. Compare form coverage, review options, data storage, hosting, collaboration, and total cost. Fillvisa OS is worth exploring if you want source-code access, self-hosting, and browser-based form preparation. Detailed product comparison pages are coming soon.
Yes. Supported free forms can be used in the browser without an account. Progress is saved locally on your device. Clearing browser data can remove saved progress, and local progress does not automatically sync between devices.
The form directory includes pages for DS-160, I-130, N-400, I-129, and more. Check each form page for availability and supported features. If you self-host, also check the forms included in your repository release.
Yes. Download a release from the GitHub repository and serve the included files with a static web server. The open-source core does not require a backend or an npm build step. Review the AGPL-3.0 license before distributing changes or offering a modified version.
No. The open-source edition uses a local browser workflow and does not include collaborative cloud features. Explore Fillvisa Plus separately if your workflow needs cloud sync or collaboration.
No. Fillvisa is an independent form preparation tool, not a government service or a law firm. It does not provide legal advice or submit applications for you. Review your answers and follow the appropriate official submission process.
