Immigration visa approved

[Venudu]

I am in INDIA, my immigration visa interview along with 3 dependents for a Green card is scheduled on 5/3/2022 through consular processing in Mumbai. (EB3). My daughter will cross 21 years on 30/3/2022.
If the Visa is approved, Do we all need to enter the USA before my daughter’s 21st birthday i.e before 30/03/2022?
Please suggest .....

There is no such thing. You have to enter within 6 months of medical date
