There's no cheat code, to my knowledge. You might be qualified to visit via the ESTA/Visa Waiver program, but you're expected to leave after 90 days. If you don't, you risk being banned from the country. There is also the possibility of H1 visas (for specialized work) or crossing over from a neighboring country. Neither of these establish permanent residency.

Or if i go there illegal is any chance that i can get papers( real one not fake ones). Or is that thing legit where can i get full documents from darkweb ?

High stakes. If caught, you're likely to be removed and banned from re-entry.
