Moving, How do I Notify?

[TomandCatie 7]

Hi Everyone!

So my husband is in the US based on his CR1 Greencard from the DCF in London.

My mother is his sponsor and we currently live with her. Her business is kicking off and she wants to now buy a house, so we will be moving in the next few months.

I need to WHEN I would need to notify, who I would need to notify and how I need to go about it?

I tried looking through the papers, but it only says "Notify us of any change in address" but doesn't say where or to who?

Thank you so much!!!
