I recently became a U.S. citizen, and now wish to sponsor my parents for green cards. I have filed the I-130 visa petition, and am waiting for approval. I understand that this whole process will take some time, and a friend of mine told me that family immigrants have to wait until their "Priority Date" comes up on the State Department's "Visa Bulletin." But I checked there, and I don't see any category for immediate relatives. Am I looking in the wrong place?
