I am a U.S. Citizen. If I file for my parents, will my brother and sister also get a green card?

Unfortunately under current law, your minor brother or sister would not get a green card if you file an Immigrant Visa Petition for your parents. Parents of U.S. Citizens are classified as “Immediate Relatives” and there is no “tag along” status for minor children. After your parents obtain their green cards, your parents could file to sponsor your brother and sister. However, there will be a wait of several years before they would be able to get their green cards.
