How to get name correction done on I94

[Chytu]

My first name on my passport has 2 names but on my i94 I got only first part leaving behind the second part. On my i797 I have the full name printed properly. my SSN is also printed correctly, Due to I94 my driving license name got cropped and both my driving license and i94 has only half part of my first name.

I checked on the forum and there is info to reach differed inspection location or CBP office within international airport. whom should I talk to ? is it inspection location or USCIS who corrects it and what is the process to do so
