“Change of address after becoming a sponsor” must notify within 30 days? : immigration

Good day,

My father (US citizen) filed for my greencard (F1/grownup youngster) in 2015 whereas he was dwelling in CA. He moved to MI in 2019. We obtained the NVC welcome e mail final week asking to add issues like his Affidavit of Help, Tax return, my paperwork. Whereas looking by means of the positioning, I got here throughout a piece “Change of Handle” that states:

When you change your tackle after you grow to be a sponsor, you might be required by regulation to inform USCIS inside 30 days by submitting Kind I-865, Sponsor’s Discover of Change of Handle. When you fail to inform USCIS of your change of tackle, it’s possible you’ll be fined.

Does this apply to my father? Undecided the way to proceed.
