Please read my comment above and stop being an argumentative pedant.

Form I-9 is primarily an employment document, not an immigration document.

The form is a requirement to be able to immigrate to the US. No form, no imigration.

You can immigrate to the US without ever filling out an I-9, if you never work as an employee while in the US.

On the other hand, a US citizen who never leaves the country might fill out dozens over the course of a career, depending on how often they switch jobs.
