To apply for an EB-5 visa, you need to submit various documents that demonstrate your eligibility. These typically include investment documentation such as proof of your investment in a USCIS approved Regional Center project and evidence that the project meets the required criteria. Personal documents, such as copies of passports, birth and marriage certificates are also required. Additionally, financial documents to verify the lawful source of your investment funds, like bank statements, and tax returns must be provided. It’s important to note that any foreign language documents must be accompanied by certified English translations. For a complete and accurate list of required documents, it’s recommended to consult with an immigration attorney or refer to official USCIS resources.
