Where do I report someone who possesses a green card, but does not live in the US nor planninig to live here, but uses the green card to conduct business, and avoiding paying taxes here and the country he is from, in other words uses the green card to launder proceeds from various bussinesses. Please let me know where would a report such a thing, maybe a phone number, or anykind of information that can help me in making such report.
Thank you
