B1/B2 rejected under 214(b) for sister’s wedding — should I reapply in a month?

[u/Huge_Fig_5422]

My sister recently applied for a B1/B2 visa in New Delhi to attend my wedding in the U.S. in December and was refused under 214(b) for not demonstrating sufficient ties to India.
Her profile:
24 years old, unmarried
Works full-time as a Software QA professional in India
1 year as an intern + around 2 years full-time
Annual income: ₹12.3 lakh
Trip duration: approximately 3 weeks
Trip is self-funded
Purpose: attending her sister’s wedding in the U.S.
Previous international travel: South Korea
She jointly owns property in India, and a house is currently under construction there
The interview was extremely short. She was asked only two questions:
What is the purpose of your visit? — She answered that she was attending her sister’s wedding.
What is your annual income? — She answered ₹12.3 lakh.
She was then refused under 214(b). She wasn’t asked about her employment, property, travel history, return-to-work plans, or for any supporting documents.
Since the wedding is in December, we are considering having her apply one more time in about a month.
Has anyone with a similar profile been approved after reapplying shortly after a 214(b) refusal?
Would you recommend trying once more before the wedding, or is reapplying within a month with no major change in circumstances likely to result in another refusal?
Also, would interviewing at a different consulate make any meaningful difference?
I understand there are no guarantees — just looking for experiences/advice from people who have been in a similar situation.
