To Shenzhen via Hongkong.

Hi,

We are from Indonesia and will go to Shenzhen 2 days for business trip via Hongkong. We will reach Hongkong on 25 Nov 13 and will go to Shenzhen after we arrived in Hkg. Can we apply Visa on Arrival (VOA) there? We are planning to go via ferry from Shekou port. Do we need other documents or just passports? Because we only bring passports.

Thanks in advance.
