marigold...like the others have said...its illegal. Yes, you COULD attempt to live together secretly, but is chancing getting caught and deported, worth it? Probably not.

Holding hands is becoming more and more prevalent, but I certainly wouldn't say it is anything like in the States or Europe. Kissing(on the mouth) in public is a definite no no. Hugs are a bit more acceptable, but only the ones that are the friendly kind..not the kind of hugs between boyfriend and girlfriend.

Think through this well before making the decision to move here and live with your boyfriend. You could always live with another flatmate and date your boyfriend. Or...if you guys are really serious, get married then move here.

Good luck with whatever you decide to do.
