Our primary mission is to seek foreign investment partners for successful US companies, not the other way around.
Unless you already live in the United States, it will be difficult for you to obtain financing on American soil for your business. The injection of personal funds is also a criterion of the E-2 Visa.
If your liquidity is limited, we recommend looking for partners willing to invest with you, this is acceptable for an Investor Visa. If your assets are not liquid, you can also get a mortgage type loan in your home country to finance your American project.
