On May 19, 2007 I arrived in HK from the USA planning on staying for 1-2 years for work (I was transferred from my company's US office to the HK office).
About 4 weeks before I left the USA I applied for an employment visa through my company. Yesterday I picked up my visa (12-month employment visa) from the Immigration Dept and it says "Good for a Single journey to Hong Kong valid for presentation on or before 09-10-07 provided travel document is valid."
I travel to Shenzhen at least once a week for business. Does this mean that I should present this visa when I come back across the border from Shenzhen to HK? If so, is my visa only valid for one entry (i.e. when I come back to HK after my 2nd trip to Shenzhen, will they let me enter on my employment visa or just the regular 90-day temporary stay visa?).
Any help would be appreciate.
