singaporeyou can apply in singapore, after you come back in June. it will take 2 weeks to do this. Last year I came back in mid of June. It's easier to get in Shang Hai and Singapore. The only one who didn't get Visa last year in my class applied in BeiJing. And I heard that all those applied in SH and Singapore succeeded. So you'd better not try in BJ, though you can apply the second time if you failed, just some money...
thx very much for the reply, but...
I have unfortunately already paid the application fee which compels me to do it in China, so it is just a matter of in which city I should do it. I also fear that I will come back to singapore rather late in the late june. anyway I am most grateful to your suggestions and if you have any other advice for me, I will be even indebted to you.
