China second Visa. Hello, what does it mean "Permitted to stay until 03 DEC 2019 this time"?
Hello, I am writing you from Suzhou, I am here with an X2 visa. As it has only one entry, and I want to visit Hong Kong (November 29 - December 2), I've applied for a second visa. This new one, with a single entry, it is valid for entry by 2020.01.05, with a duration of stay of 35 days, and that's ok for me, as I will fly back to my own country December 6. The problem is that under "observations" it is written "Permitted to stay until 03 DEC 2019 this time", and I really don't understand it. Does it mean that to use my new visa I have to leave China before December 3? In this case it is ok (I fly to Hong Kong November 29), but my flight back to China is December 2, one day before! Or does it mean that my old visa will expire on December 3? I really don't get it. Thank you in advance for your help!
