The O-1 visa is a “dual intent” visa, which means that if you qualify for a green card, you can transition from O-1 temporary worker status to permanent residence status without any interruption in your visa status and without having to leave the United States.
The US government offers many different types of visas for those who would like to come to the United States to work. The O-1 visa is designed for people who have demonstrated extraordinary ability and achievement in certain fields, and who intend to engage in that occupation while in the US. O-1 status offers quite a number of advantages that other employment-based visas lack.
