I met a few people with US work authorization keeping a US residence in a no income taxed state (Texas, South Dakota) and maintaining a job with that residency. They pay US federal and employment taxes. Some of them report this income to their other country of residence, whereas other do not. Some are nomadic not staying in one country long enough to be considered a tax resident. It's a legally gray area. In EU, unless they have dual citizenship or a legal reason to stay in a country for a while, they hop around due to visa issues and leave the Schegen zone to non-Eu/non-Schegen countries like Morocco, Turkey, Georgia, Romania etc. Many are in Central/South America due to time zone simplicity. good internet is a must. Do note many countries have a digital nomad visa option.
