Yes, an EB-5 immigrant has authority to work in the United States. No, you are not required to work for the EB-5 regional center or any of its programs. You will be able to work in any job in the United States for which you are hired. There are no restrictions applicable to EB-5 immigrants. Of course, all persons must obey the laws of the United States and refrain from illegal conduct.
Under the EB-5 program, upon approval of the I-526 petition, the foreign investor and his immediate family may apply for admission to the United States as conditional permanent residents. A permanent resident has a right to live and work in the United State without any restriction.
If the foreign investor and his immediate family are physically present in the United State while the I-526 petition is processing, there is no authorization to work until the I-526 is approved. The investor and family may then file to become conditional permanent residents and for work authorization.
