To effectively verify and track the accreditation of offshore investors, use platforms like Accredd, which streamline the verification process and ensure compliance. Non-US investors must meet the US accreditation standards to be LPs in a US fund. This typically involves meeting specific financial criteria, such as income or net worth thresholds. Additionally, fund managers must adhere to both US regulations and the regulations of the investor's country. Consulting with legal professionals is advisable for compliance.
