The problem is that my daughter is in China after summer break. Yesterday, I sent an email to 香港入境事务处, they just replied me an automatic email and that email told me to send a mail to 香港入境事务处 office. I guess that would need a few days. I wondering if there is a phone number for us to call 香港入境事务处 and hope that there is someone can response my call.
Thank you for your logical idea.
