Foreign Real Estate Investment in U.S.

I know this sounds funny. Not sure if this is the right chat about this but essentially I have a family connection from west Africa who has essentially over 9 figures, probably close to 10 in dollars in their country’s currency. I’m in the CRE industry and he reached out to me about investing, he plans to pay all cash for all deals. The problem is getting the money to the US. There’s no banking relationship with the U.S. in that country. How can we get a few million over or do you know anyone who can help?
