| When you come in come in on the visa and get it stamped at immigration, don't worry about the single journey (it refers to first one). You come in, get visa stamped and they put date to leave HK by (one year probably), when you come back just come back in on that one and you will get exit stamp to end of visa rather than the 180 days.
To be honest don't know of anybody who has ever been asked about return tickets in HK |
