Earlier quoted context omitted.
Many of them hire you as a contractor, of course. However, I noticed that more and more companies use an "HR as a service" (e.g. deel.com) to act as an intermediary who has an official branch in most countries and takes care of all the formalities for you.
I move between countries. Anyone happen to know how this works for this situation? (i.e. I'm currently in Mexico, but next week I'll be in Guatemala. Does Deel cope with this, and if so how?)
For my situation setting up my own us llc and contracting/consulting through it means I can move around. Also the us llc onboards cleanly for any companies using gusto and for others I send a W9 that they know how to handle.
