给美国大使馆写信要求换签证
To American Embassy to China:
Dear Sir:
This is to request a change of my destination for my planned trip to the United States. You have approved my visa for attending Roosevelt University in Chicago to pursue an advanced degree in Chemistry. Fortunately yesterday I received another 1-20 form issued by the University of Oklahoma which admitted me to graduate study in Hospital Pharmacy. As I am a graduate of the School of Pharmacy, Beijing Medical University. the study of Hospital Pharmacy will be more beneficial to my future career in China. Thus, I prefer the University of Oklahoma to Roosevelt University.
I am enclosing the 1-20 form issued by the University of Ok lahoma. It is requested that you permit me to change my destination from Roosevelt University to the University of Oklahoma. Your assistance will be greatly appreciated.
Sincerely,
