If you have ever been granted a China visa on your passport before, you may just apply for a Shenzhen on yoru arrival at the entry port. If you have never been to China before, you'd better apply for a China visa from the visa office of PRC in HK SAR in advance. An on arrvial visa at the entry port of Shenzhen costs around 168 RMB. The cost of a China visa in Hk costs 220 Hk dollars.
