Dear Sir,

I'm working/living in Kiev (Ukraine).
My nationality is Repulic of KOREA.
(I have an ukrainian work permit. residence certificate)

I'm going to china in middle of May (1~2 week) as biz trip.
In this case, do I apply for Tour visa(L)? or single entry Business visa(F)?
Could you let me know how long does it take to get original invitation?
(via travel agency / chines company (invitor))
Cuz only one month remains before my leaving.
which one is better?

Also, can I apply visa by myself?
in case of chinese consulate in KOREA, they doesn't permit it.
only authorized agency can submit the document behalf of me.
How about Chinese consulate in Ukraine?

Please kindly advise me.
Thank you in advance.
