You can stay in the U.S. on an H-1B visa for up to 6 years, usually granted in two 3-year terms.

The standard duration is 3 years, with a possible extension to 6 years in most cases.

An H-1B visa is initially valid for up to 3 years and can be extended for another 3 years, making a total of 6 years.

H-1B duration is job-specific, so any significant job change may require a new petition and approval.
