5-day visa at Shekou Port

Hello,

We are 3 French people in Macao, is it possible to obtain entry permit for Shenzhen this Sunday in Shekou Port ? In the information above, we can read that the 5-day visa "is available INTERMITTENTLY at Huanggang Port, Shekou Port and Fuyong Port." Our plan is to take the ferry from Macao to Shekou, get entry permit there and spend a few days in Shenzhen.

Thank you in advance,

Lauriane
