Do you want to apply for the 5 Day Shenzhen Visa On Arrival?
If yes, you need to show your valid passport first. The five-day VOA is a sticker pasted on the passport like a regular visa. Hence, there must be at least one blank page in the applicant's passport. Complete the application form when you are at the port. Then The officer will take a photo of you after you hand over your passport and application form. Pay for the VOA; there is a window for currency exchange.
