Assume a US citizen currently located in the US, and whose location and identity is verifiable (say using their home IP address), connects to a commercial VPN server physically located within the US borders, but the server is operated by a foriegn company (e.g. NordVPN, ExpressVPN, ProtonVPN). Assume the communication takes place entirely within the US borders. Can government agencies like the NSA monitor and store the communication without a warrant under FISA or similar acts? Is it considered a domestic communication? Is it considered to have foreign intelligence value automatically due to the fact that the company is not based in the US?
