What are the requirements for an ordinary worker, who isn't necessarily "amazing", to get a work visa sponsored in the USA? The employer has to conduct a bona fide search locally and show that they were unable to find a local worker to do the job as well as the remote worker? What if the remote worker was already working remotely, and knows a lot of the codebase etc. ?

Would something like this visa be most appropriate: https://www.uscis.gov/working-in-the-united-states/permanent...
