So you let company underpay you and then you move to a cheaper country in order to survive?
Bum-engineer visa sounds more appropriate. Why engineers don't value their skills?
Who said anything about letting a company underpay you?
Most do a digital nomad setup in order to have fewer living expenses and therefore more quickly save up and retire early. Nothing about working for less money while doing it.
I expect most digital nomads don't work for employers--though I've known limited time exceptions within the US. For employers, I imagine it would create tax and accounting headaches and, while people can and do have working vacations and such, that's different from heading to Thailand for three months to work remote.
