I am new here.
I am studying in China (Beijing), and I have an opportunity to go to Spain (Valencia) for summer school in this July for one week. I have Vietnamese citizenship. I would like to ask some questions that:
Do I need to apply for a visa to enter Spain?
What kind of visa must I apply for?
How long does it take to get the visa?
How much does it cost?
What supporting documents must I provide?
Any suggestion for me when I travel to Spain?
