Las Vegas, Nevada.

I need to file the form I-102 to replace my I-94 ASAP!
-My only concern about :

Can I do it by my own, without hiring a lawyer to receive a replacement ???.... or
are there any risk of disclousing my address on the request ?
Does the USCIS may take action aginst me knowing my case, without having a law firm requesting it for me ?

- Thanks a lot for your value time and help.
