Does school administration directly contact to your fellowship foundation?

[qingqing]

Hi,

I'm an international student and I've been given stipends for my PhD.

Recently I received cash awards from a private foundation in my country for economical support because I need support to live with my wife and children.

Now, the grad school requires me to submit an official letter and terms of awards which are all in Chinese. They are going to deduct an amount of award I received from the stipends I am being given.
Do you think they are going to directly contact the foundation in China, or do they just need this for their administration process?

I'm worried because if the foundation knows my grad school is taking the whole money, they are going to cancel it.
