但是我在学校q&a上面见到以下的话:with effect from january 1996, except for some countries, overseas students normally do not require a re-entry visa to resume their studies in hong kong provided that they return to hong kong within the limit of stay imposed with the student visa and that there is no change in circumstances since last departure. in any case, you should check with the immigration department first before you leave hong kong.是不是意味到澳门还要格外的手续神马的?
