Dear Sir/Mdm, I am currently in Hong Kong for visiting my friend and plan to go to Shenzhen, but the immigration at border rejected me to have visa-on-arrival. They suggested me to get the visa back in Hong Kong. My question is how long will it take to get the visa because I will not be long in Hong Kong and probably you could also inform me the fees and any documents required.

Thank you for your cooperation.

Best regards,

Eri
