Yeah, something like any S'pore company anywhere as long as you pay taxes to S'pore, which isn't really that bad since the income tax is pretty low anyway.
A few of my peers are all over China and Malaysia with S'pore companies. One even went to UK for training and counts for the 3 years. But I don't know how the account for it though, like do you have to have a time chart like how many hours you clocked with company A, then company B etc. ?
