Hi, two of my former students from the University of Qinghua, Zeng Ming and Zeng Zhi, will attend the TIPP conference and then stay two days extra to work with me.

Can we please provide them with letters of invitation until June 9, to cover the entire periods of their stay?

Thanks in advance for your kind help, regards Antonio
