In order to work in the United States you must have authorization from the USCIS.
Work authorization comes in a variety of forms and the form that is appropriate in your case will depend on several factors, including, but not limited to, your level of education, the type of skills you possess and the U.S. demand for workers in your field.
Generally, the first step is to find a job.
