Both the O1 Visa and the EB1 Visa are targeted at highly-specialized professionals. Nevertheless, they still have several significant differences.
The EB-1 permit in an immigration visa, meaning it can be used to live and work in the U.S. permanently. On the contrary, the O-1 Visa is a non-immigrant permit that can initially grant only a temporary stay in the country.
The O-1 Visa is usually one of the most desirable U.S. permits since it is not subject to annual caps, unlike other visas. In addition, there is no set level or education nor minimum wage requirements. Nevertheless, you must possess extraordinary ability in your field to qualify for this permit.
While the O1 Visa is open to different professionals, the EB1 Visa category is not tailored to those who work in media and television arts. On the other side, EB1-1 Visa applicants do not necessarily need to be sponsored by their employee to apply. In the case of EB1-2 Visa, only the most outstanding professors and researchers are selected to enter the U.S.
Only the immediate relatives of an EB-1 Visa holder are granted Green Cards upon approval. If you hold an O-1 Visa, your family members can still apply for an O-3 Visa.
