Travel to US with grand mother before 15 days of expiration of visa

Hi Kumar/Team,
My kid is in India currently planning to come US in april along with grandparent but his visa on passport expires on April 20, 2021.
Recently I have changed the company and transfer got approved. He has old visa on passport.
Is it ok to travel with old visa, new i797 with 10 days before the expiration of old visa?
