Student Richard O'Dwyer said he is looking forward to returning to normality after striking a deal with US authorities over his TVShack website.
"I'm happy it's finally over," he told the BBC. "I still maintain I never thought I was committing a crime.
"I'm glad the US has decided to drop the case. It's a pity the UK wasn't able to resolve this."
He added: "I'm looking forward to getting back to university and see all my friends."
- Richard O'Dwyer could have faced jail if convicted of the allegations.
- The allegations were brought following a crackdown by the US Immigration and Customs Enforcement agency.
- The agency claimed the TVShack.net website earned more than $230,000 (£147,000) in advertising revenue.
- US authorities obtained a warrant and seized the domain name in June 2010.
- It is thought Mr O'Dwyer will return to the UK with his family today.
Earlier this year Home Secretary Theresa May approved Mr O'Dwyer's extradition, which he appealed.
Richard O'Dwyer's deal with the US is "a first" in extradition cases, his lawyer has said.
Under the agreement, O'Dwyer must pay US authorities £20,000 and not break any US laws, "associate only with law abiding people" and work regularly in a lawful occupation.
A student who ran a website where users could stream pirated films has "avoided a conviction" after paying £20,000 to US authorities, his lawyer has said.
Richard O'Dwyer, from Sheffield, ran the TVShack website hosting links to pirated films and TV programmes.
But after a court hearing in New York, the 24-year-old avoided extradition and conviction by signing a Deferred Prosecution Agreement.
As a result he paid £20,000 to the authorities, representing the profits he made from TVShack between December 2007 and November 2009.
The money will be distributed among victims whose copyrights were infringed by TVShack.
