Do I require visa stamping?

Hello guys I'm on h1b recently I found a fulltime opportunity and I have a h1b stamping done with my previous employer valid upto 2025. And I'm planning to get married this year will I be needing to get the h1b stamping if I go to india? If not required will there be any complications coming back to usa? If I plan to get my fiancé get visa stamped I should be using the new approved visa will that affect my coming back to usa? TIA.
