I'm a US Citizen and my parents are Permanent Residents I have a few questions:
1.If I want to apply for my sister's I-130 Form how do I immigrate her husband and children aswell
2.Am I required to fill different forms for each of them , if not
3.What additions should I make to her I-130 form
4.Does having a child approaching the age of 21 give higher priority
5.What would be the fees for applying for her whole family of 5
