Eh, not really? If it's a legit company who provides services to various governments, they're going to pay you, they're going to report the income to the government, you'll get a 1099 for contract/consulting, and you'll pay your taxes on the legit income. No red flags. Assuming they're legit and not currently sanctioned by the US government that is.
