This makes me laugh. I am 41(female white US citizen) and my fiancé is 27 Pakistani male. The CO who interviewed my fiancé never once asked him if he was concerned about our age difference nor was she alarmed by it. Age is just a number and when it’s a real relationship and you can see and hear the love the person as for the other these “differences” won’t matter at all!
Good luck to you. May Allah SWT help you worry less
