Hong Kong to Beijing for an American

Hi there,

Just for clarification want to make sure I'm interpreting the 72 hour visa correctly...

I'm an American and will be spending several days in Hong Kong (ATL to HKG then HKG back to ATL).

While in Hong Kong since BJ is pretty close I wanted to buy a flight RT flight from Hong Kong to BJ to do a quick tour of the Great Wall.

Will this be ok or do you foresee issues?

Thanks for your feedback!
