Yes, you can fly under VFR (Visual Flight Rules) into Class B airspace, but you are strictly required to obtain an explicit ATC clearance before entering. Unlike Class C or D airspace where simple "two-way radio communication" is enough, a pilot in Class B must hear the specific phrase: "Cleared into the [Name] Bravo Airspace." Additionally, the aircraft must be equipped with a Mode C or Mode S transponder with altitude reporting (ADS-B Out is mandatory in 2026). For the busiest "Primary" airports within Class B, the pilot-in-command must hold at least a Private Pilot Certificate (student pilots are generally prohibited from landing at these hubs). Once inside, VFR pilots are provided with radar separation from all other aircraft. Failure to obtain clearance before crossing the "Blue Line" on a sectional chart is a major FAA violation that can result in immediate pilot certificate suspension or significant legal penalties.
