Actually it depends on the type of visa. If you are on a tourist visa, you are not allowed to work. You forgot to mention US may be because it's your home country, but it is illegal to work in US on a B1 visa. Edit: also, if you are in US on work visa, you are supposed to declare any income you receive in your home country, and you are taxed on that money, even if the home country already taxed it.
