So I just got an informed delivery from usps that there’s two mails from uscis coming, I know one is for the i130 approval notice,because our i130 was apeoves about a week ago,but what could the other one be?because one is addressed to my wife,(most likely the i130) and one is addressed to me and I’m thinking what could that be?

Anyone with similar experience kindly help thanks.
