The controversial Sex Island resort that offers unlimited romps with 100 women could soon be shut down.
It's believed 30 men, including 13 Brits, have bought tickets to the erotic orgy event.
It has previously been held on Isla Margarita, off the coast of Venezuela.
This year, the X-rated event is scheduled to take place at an undisclosed location in the US state of Nevada - the only US state where prostitution is legal.
But authorities have insisted they will take severe action if the party breaches any state drug or prostitution laws.
The getaway has been slammed for being "drug-friendly", where guests claimed illegal drugs such as cocaine and LSD were easily accessible.
America’s Drug Enforcement Administration (DEA) issued a warning to event organisers, The Good Girls Company, saying they will make arrests and deport any guests breaching drug laws.
They also warned to take action against the event if prostitutes are under the age of 18.
The warning reads: "All foreigners attending and caught handling illegal drug substances will be immediately taken into the nearest immigration detention center and processed for deportation.”
A spokesman for The Good Girls Company said: “The authorities are clearly getting nervous about Sex Island coming to the US for the first time, but they know they can’t stop us in Nevada so they are warning us about illegal drugs.
“We have reassured our guests that they don’t have to be worried about being deported. Everything will be legal and above board.”
The event, held every year on August 2, will take place over a span of four days where guests pair up with two women to take part in a range of sexual activities.
The four-day X-rated holiday costs around £4,600 per person.
The men will take part in q series of "sexual surprises" including a "sexual helicopter tour" and a "holographic concert".
Guests will be paired with two of the 100 women during their entire stay, with the choice to switch partners at any time.
Last year, a 16-year-old teenager admitted to losing his virginity on the island.
The teen, who goes by the name of Brian, told the Mail Online: ”It was incredible, so amazing that I want to cry just thinking about it.
"I had sex for the first time, alcohol for the first time and I did drugs for the first time."
The teen added: "Every guest was allowed to choose two girls who would spend the entire vacation with them. One of my girls was called Andrea, and I fell in love with her."
