Hi guys,
I'm leaving to study in China on Feb 19 next year (for a whole year), and I'm aware that I need to get a Student X Visa and extend it within 30 days upon entry into the country. Before I leave for China, however, I will also be going to Taiwan on Nov 20 to study there for 3 months. Obviously I need to get my visa before I leave Australia (can't get it in Taiwan).
I've been searching on some sites and it says that the Student X Visa is generally valid for 3 months and good for one entry only. What I want to know is: can I get a double entry Student X Visa (6 months validity) into China, or is single my only available option? As I said, I'll be leaving for Taiwan for 3 months before I head over to China, so a single entry Visa would be far too risky.
I hope someone can make sense of all that and kindly help me out? Thank you so much in advance. :)
