How to withdraw an application with USCIS?

[ker2usa]

I filed an EAD i765 will USCIS and would like to withdraw the application. How can I do this? Is there a form or do I simply write a letter to the concerned USCIS office? Thank you.

As it turns out, simply sending a letter stating reason for withdrawal, case number, and proof of receipt was sufficient for USCIS to withdraw the application.
