Thank you for your inquiry of 5 day Shenzhen visa. Most European and developed countries are eligible for the 5-day visa, including US, UK, Canada, French, Australia, Germany, Korea, New Zealand, Poland, Romania, Spain, Sweden, and Switzerland. Because we do not know which country you’re from, so there is a possibility to be refused for you. Citizens of countries not mentioned should contact the relevant Chinese embassy or port to ask if they can apply for the Shenzhen visa on arrival. If you are traveling for business, please consult your local immigration center.
