Dear Sir,

I am a Professor in Physics at Peradeniya University and I am planning to participate in a research conference on Physics in Wuhan as an invited speaker from 2nd to 6th May 2010.
I have got the letter of invitation from the organizers (Wuhan University).
I also have the following documents ready:
Valid Passport, completed application form and photograph.

What else do I have to produce when applying for visa.

Best regards

Prof. M. Dissanayake
