For an EB-5 visa application, you must demonstrate that the capital you invest was acquired through lawful means. This envolves providing detailed documentation that traces the origin of your funds from the point they were earned or acquired such as salary, business income, inheritance or the sale of assets, to the point of investment in the U.S business. USCIS requires this to ensure that the funds are legally obtained. Documentation can include tax returns, bank statements, business records, sale agreements or other financial documents that clearly show the source and legitimacy of the money. Failure to provide sufficient evidence of a lawful source of funds can result in a denial of your EB-5 petition.
