hi, I am planning to go to Beijing for chinese language study for 2months. The school said that I just need to acquire tourist visa and then we'll change it when I get to china. Now, I have to purchase my roundtrip tickets as a requirement for getting L-visa. HOw many months is L-visa valid anyway? If my ticket departs on May and return is on August, will that be okay? Would I pass to get the L-visa? I am really confused. Thank you for you help.
