DURATION OF H-1B STATUS

Initially, you may obtain H-1B status for up to three years. Prior to the expiration of the three-year period, you may apply to extend your stay for an additional three years. In general, at the end of the six year period, no further extensions of H-1B status are permitted. Although you are allowed to change employers by submitting a new petition to USCIS (accompanied by a new LCA from DOL), this does not waive the six-year limitation.

Extensions after six years are possible for certain persons who have experienced lengthy delays in the adjudication of their applications for labor certification or for employment-based visa petitions, or for H-1B holders who are unable to adjust their status in the U.S. because of per-country quotas.

Therefore, if you wish to apply for permanent residence, you should begin this process as early as possible after you have located satisfactory employment.
