Filed I-130, now addresses have changed

I filed an I-130 petition for my sister to get her green card back in 2001. Back then my sister lived in India and I lived in Boston. But now, I live in Maryland and my sister is here in the US on a work visa. Im guessing I need to notify the USCIS about both address changes. Is that true, and how would I go about it?
Would appreciate any help.
Thanks,
CTF

Go to USCIS at this link and change your address:

https://egov.uscis.gov/crisgwi/go?action=coa

yes, you need to!

You should update them, unless you are hoping they will be able to guess the updated address for yourself and your sister
