| Depends on when you're departing. If you travel during peak hours then there will be some queues, but the ones at the ferry terminal are generally pretty quick and you should be able through in 15-20 minutes if you have all the necessary travel documents ready.
The ones at the airport in Shenzhen are not as crowded as the ones in HK as comparatively fewer people travel by air from Shenzhen. But factor in at least half an hour to get through immigration queues if you're taking a regional flight.
Again, the earlier you go, the better. Have a safe trip. |
