My girlfriend and I have been dating 3 years and she is a native Hk. I live in the USA and plan to visit HK near the end of the year . I'd like to stay for longer than the 3 months normal entry gives me. Any way to get an extention to maybe 6 months or a year? I've heard people say it is possible to go for 3 months, take a trip to Macau or the Mainland and then re-enter for 3 more months. Is that legal? Doable? If not, what might be another way to get a longer stay without the obvious "work visa" or marriage route?
