This is one of the biggest problems with our immagration system..chain migration where one person gets approved and they get to bring their neighborhood with them....you and your immediate family only per one work visa....those people will live off of that paycheck the work provides that the Visa made possible....if someone else in the family wants to come they can apply for a Visa as well... or maybe once you've been an established resident with good track record then possibly be able to apply for more outer rings of family like grand parents and siblings
