My father is a Canadian citizen and living in US as visitor. He is elderly and does not have family support in Canada anymore. My brother who is also a Candian citizen lives in New York and works
as a physician. He is the caretaker for my father. I am a US Citizen living in California and would like to apply for green card application for my father so he can stay in the US permanently with my brother.
question 1: my father a Canadian citizen entered the U.S. via land does not have I-94. Can I skip I-94 related questions in I-130?
question 2: can my father travel to Canada and back to US after I-130 is filed?
question 3: Do I need to file affidavit of support with I-130?
question 4: Is there option to expedite his GC processing given his advanced age?
