GC based on US citizen minor child

[WhyThisDelay]

My brother's child is a US citizen based on fact that he was born here. But my brother is neither a citizen nor green card holder.

My question is can he apply for green card based on the his newborn US citizen child?

No, he'll have to wait until the kid becomes 21 years old before that child can apply for his father.
