US citizen parent can petition for unmarried children in the "Immediate Relatives" category and immediately visa is available for that child to enter US. For children married or older than 18 years of age the wait time is more and visa is available once the priority date becomes current.

So this process is more time consuming and time taken depends on the state where you apply and based on applications pending.
