I require a thorough understanding of the distinctions between the EB-2 visa and the F1B visa, particularly as they relate to family-based migration strategies. Please provide detailed information on qualification criteria, processing durations, and long-term objectives of each category. It is important to know how dependents—such as a spouse and children—are accommodated under both visas, including their rights to reside, study, and obtain work authorization (EAD) in the United States. I am also seeking clarity on the length of stay permitted, the feasibility of status renewal or adjustment to permanent residency, and the overall security offered by each visa pathway. My intention is to determine which option provides the most sustainable route for professional advancement and family settlement.
