For people running a small business that is remote/can be done anywhere (a small SaaS company for example). What are their options for operating in the US?
To give a specific example. An indiehacker runs their own business, and wants to move to the US, potentially with the view of trying to become a citizen at some point. They have plenty of income, don't need a job/so don't really have a visa sponsor etc.
What steps should they look to take?
