Typically, B-2 visa holders are granted a stay of up to six months (180 days) per entry, as determined by the Customs and Border Protection (CBP) officer at the port of entry.

If you wish to stay longer, you may apply for an extension of up to an additional six months, provided you file Form I-539 before your current authorized stay expires.

The actual length of stay granted is at the discretion of the CBP officer; while up to six months is standard, shorter durations can be assigned based on the specifics of your visit.

There is no official annual limit on the total number of days you can stay in the U.S. on a B-2 visa; however, frequent or prolonged stays may raise concerns about your intent and could affect future entries.
