Hello, sorry to bother people with this small question.

I'm studying at University in Japan at the moment and I want to visit China to see some friends. Because of my schedule I'm only free during weekday afternoons and weekends, but the Office Hours of the Consular Office are 9am until 12. Is this definitely the only time I can go and apply for my visa? My school holiday starts on 25th February, and then I fly to China on 11th March, so I could apply then, but is that leaving it too late?

Thank you for any help you can offer!
