你draft 封信(quote your VCAC#, your ID Card No., helper's name, and your reason)fax 去入境處, 可加快1-2 week, 中間最好打電話follow up, 我agent 話如電話follow up 你要quote helper's passport no. as well。
I called the Immigaration Department today and they replied to me that my helper's working visa will be issued within this week if everything's ok. Then I told my agent and she said my helper will be arrived at HK by June 24 the earliest.
