The EB-5, Green Card through investment, was created to promote investments in businesses and to create and preserve jobs in the U.S. You can become a lawful permanent resident by establishing a new commercial enterprise and provide full-time employment to at least ten U.S. citizens, legal permanent residents, or other immigrants with employment authorization.
Show, using reasonable methodologies, that 10 or more jobs are actually created either directly or indirectly by the new commercial enterprise through revenues generated from increased exports, improved regional productivity, job creation, or increased domestic capital investment resulting from the pilot program.
