If you already work remotely then just go. No need to get permission. Taxes are the same for US citizens (eventually FEIE kicks in, a benefit to you). Unless you have a work permit in the foreign country you are either working illegally (enforcement close to nil, say you are a tourist when entering) or you have a long-stay visa that allows remote work — many countries offer such visas now. This is the digital nomad thing. Another route is freelancing. You just keep your US bank accounts and set up a mailbox, line up clients. I did this for six years and not one client cared where I was as long as I answered emails and phone calls promptly. I started traveling when I had a f/t remote job, I just started traveling, no one asked or cared.
