Well, as it seems to be somehow in the public interest 😉, I've asked them myself. From what I have heard, the price is strictly tailor-made according to what is requested, beginning from just-a-person-in-the-files doing close to nothing and spending on it ~a hour monthly and ending with managing an accountant and a part-time office worker, signing contracts and engaging external lawyers, all on the almost daily basis... In numbers, none of their clients is currently charged less than USD 400/month, the upper limit they have not shared 😉. From what I witnessed, their hourly rate begins at USD 275.
Yes, I agree.︅ Perhaps I'll add as a reason to hire a nominee, if you have some passport︆ (or a residence) with really a bad reputation in the US – in the same︇ time being completely OK personally.
