Hi,

 

Are letters of recommendation submitted electronically must be signed? 

 

None of the universities I'm applying to explicitly stated that the letters must or should be signed. I'm applying to these universities:

 

UC Berkeley

Standford University

UC Merced

University of Southern California

UC San Diego

UCLA

UC Santa Cruz

UC Santa Barbara

UC Riverside

UC Irvine

Caltech

 

Best,

The application will provide all necessary instructions to the professor. You don't have to worry about this part.
