How long can one maintain O-1 status?

There is no set maximum period for O-1 status. Theoretically, it can be indefinite. However, the length of the status is determined by the length of time needed for the alien to perform his duties or activities with the petitioner employer.

An initial stay is limited to no more than three years, provided the petition can establish that the O-1 alien will need this much time for the proposed employment. This period may be extended at one-year increments thereafter, upon evidence showing that the alien's continued presence would be required.
