Change of Status from H1B to F

Hi

I have applied for COS from H1b to F2 as my wife in on F1, however, got an RFE where USCIS is asking to “submit a statement and evidence detailing the effect your extended stay in the United States will have on your foreign residence”

What exactly we have to provide on this? Could someone help us understand what needs to be done here?

Thank you in Advance
