Beyond the qualifying capital investment, expect administrative fees charged by a regional center where applicable, USCIS filing fees for the immigrant petition and adjustment or consular processing steps, and professional fees for legal and source-of-funds documentation work. The stages run from petition, to visa availability, to an immigrant visa or a legitimate adjustment of status where you are eligible — and in some situations a qualifying EB-5 filing supports concurrent adjustment, so the steps are not always strictly sequential. Place current petition information and the applicable immigrant-visa or adjustment steps in a new chronology rather than advancing dates simply because a similar project once moved faster. Government charges apply at several stages, including the initial petition, the immigrant visa or adjustment stage, and later the petition to remove conditions, and current amounts should be taken from the published fee schedule.
