I don't violate foreign laws if I buy a goods online from another country. I don't need to know anything about laws governing manufacturing to purchase a screwdriver made in California. I only need to know my own laws. Is it legal to import screwdrives in my jurisdiction? Yes. Can I do this transaction without violating my own sanction laws? Yes That's it. Whether the California entity is allowed to sell to me is their problem, not mine. The same applies for labor. I want to buy foreign labor? I negotiate the price, I get the work, I pay the invoice. Which laws do I consult? Every potential country-to-country mix in the world? No, I consult my own laws. Is it legal to purchase foreign labor/services. Yes. Can I do this transaction without violating my own sanction laws? Yes Whether I buy a website or a screwdriver - I do not need to know anything about who I'm buying it from beyond the necessary information to avoid international sanctions.
