As an Indian citizen, I can get a visa on arrival in HK for a stay up to 14 days.
If I had to stay for longer, say 20 days, is it possible to leave Hong Kong for Macau/China and enter again? To be more precise, I leave HK on the 13th day of my contiguous stay and arrive back 2 days later to stay for another week or so.
Is there a potential problem with this plan?
