Chen Ryan Ma I don’t want to share too much, but if you're in the US, there are several companies that offer work from anywhere, each with their own policies—Pinterest being one of them. Many others do as well, but their rules vary, so I’d recommend doing your own research to find the best fit for you. That said, I also know A LOT of people who work remotely and just travel around without officially getting authorization from their employer—they simply just bounce around on a tourist visa.
There is no income requirement. However, if your salary is quite low, I’d suggest keeping a significant balance in your account for a longer period to show that you can support yourself.
