Dear Sir,

My thai girlfriend will be meeting me in Hong Kong and then later go to Shenzhen together for holiday and sightseeing.

I understand that for Thai citizen, she does not require to apply for any visa application as Hong Kong is visa-excempt. How about Shenzhen, China? Must she apply visa application? We will be in Shenzhen for about 6 - 7 days. Will it be single or double entry visa application? Must she give any reason for visa application (reason = holiday?) We will then go back to Hong Kong for some sightseeing before departing back to Bangkok. Please advise. Thanks! D.
