How old are the over-age children of American labor immigrants?

There are no labor immigrants in the United States, only work visas. After working for three years, they will apply for a green card according to the conditions at that time, and it will take more than two years to be approved.

Whether you are an adult or not is calculated when you submit a green card application. If the child is under 2 1 year old when submitting the green card application, you can submit the application together.
