Visa Application - Singapore

Hi All,

I'm a Singapore PR, and have been in Singapore for few years. My boyfriend has a plan to come and live with me in Singapore for a year before we move out to somewhere else (We are tired of the long distance).

We are not married and he doesn't have a plan to look for a job in Singapore because his company (based in New York) allows him to work from anywhere around the world.

Anybody knows what visa should he apply for (at least the one that is valid for one year ahead)?

Thanks.
