Hi i am an Irish citizen and would like to travel china. do i need visa?

Zakir, in normal cases, you need to get it prior to departure. The required documents for the application include: 1. your passport and a copy of the used pages; 2. an application form attached with your recently-taken bare-headed photo; 3. fly-in and fly-out tickets and hotel bookings. Besides, if you apply from Bangladesh, you need to show the original and copy of your residence permit there.
