Dear President Yang

I am writing this letter asking your special help in regard to 
Dr. Guansong Zhang's application for a waiver from the 
"two year service rule" from HIT and Chinese government.

According to U.S. immigration law, a J-visa holder, as in Guansong's
case, can only work three years in the U.S.A., unless he can get a
waiver from his own country.

During the past two and half years, Guansong's work at NPAC has included
some impressive achievements including an HPF compiler and Fortran to 
Java translator. These technologies are good examples of the benefits
of the collaboration between HIT and NPAC which combine the talent of
your staff with the benefit of working in NPAC's projects involving 
many major universities and other organizations in the U.S.A.
I am sure that Guansong will be a great asset to HIT if he
come back to your university. However as an honored professor of HIT, I also
believe that it will be more beneficial if he can continue to work at NPAC.
This will help not only NPAC but also HIT, because the cooperation relationship 
between the two institutes will allow our leading edge projects to
continue to feed knowledge and contacts into HIT. 

So I hope that you can assist his application for the waiver, and
your effort in this regard will be greatly appreciated. 

I understand that his application material including an appointment letter from
NPAC has been sent to HIT already. However I am of course more than willing to 
provide any additional documents you need. 

Since this is a timely issue (Guansong Zhang's visa will expire on 15th
this October), I am looking forward to hearing from you as soon as
possible. I thank you for any help you can give

Yours respectfully
