Sponsoring parents and brother

[haresh]

Hi ,

This is from my friend who need some help.
===============================
I am getting USA citizenship this month. I already passed the interview.

I have my parent and brother in India, whom I want to sponsor.

1) Can I sponsor my parents as well as my brother at the same time?
2) My brother's current age is 19. I know there is some rules around age out. In what case, my brother would be qualify /disqualify the immigration benefits. ?

Thanks in advance.
