The following information was found on the TEALIT forum:
"I called the HK office several times last week:
They did confirm me that from 1st december rules will change and that they might not be able to make it on the same day.
The fact is that now you might get your visa in the afternoon on the same day you applied; however they simply won’t guarantee anymore that you’ll get it!!!
The reason I was given is that their office gets very busy. I was also said that too many foreigners complain about delays in their visa issuance…"
Did anyone hear about that?
