I am seeking a professional comparison between the EB-2 visa and the F1B visa, specifically in the context of long-term family migration planning. I would like a detailed explanation of their eligibility requirements, processing timelines, and intended purposes, along with how each visa accommodates dependents in terms of residency, education, and work authorization (EAD). Please outline the typical duration of stay, renewal options, and the possibility of adjustment of status to permanent residency under each category. My primary concern is identifying which visa provides a more secure and practical pathway for both the principal applicant and family members, balancing professional opportunities with long-term family stability in the United States.
