For those curious, a common method is to publish the job listing in the newspaper classifieds.
This is what my old employer did to sponsor the visa for the company’s CTO.
Newspapers are used for a surprising number of various public announcements. E.g. in New York you must publish a notice in a newspaper for 6 weeks (or something like that) when establishing a LLC.
There’s something to be said for reading the paper even in 2025! Although I suppose the notices are probably also online..
I've also seen this done when the hiring manager, or someone else in the process, already has a candidate to hire and needs to post the job listing for legal cover.
