These are usually not worth it for most digital nomads in my experience. Another option for those who don't want to do it is create a company in US (dont need to be citizen or have bank account) and pay flat rate tax of a couple hundred a year then travel on tourist visas. This way you avoid most of the tax implications of the country you are in (most countries have tax charters which allow you to only be taxed in either US or there - not both) and in US as they only charge you tax if youre clients are in US AND you are psychically sending things to US clients.

This only works if you aren't already a US citizen in which case you cant avoid the case as I understand it. In that case maybe these are fine or you could look into creating a company in Europe and doing something similar.

Lots of ins and outs to this but there are some tips!
