The Army said Wednesday that Manning remains subject to the military's criminal code until her discharge from the Army, and that her "excess leave" status will be lifted if she's prosecuted for any violations.
In July 2010, Manning - then a male soldier known as Bradley - was arrested over the release of a huge trove of more than 700,000 classified military and diplomatic documents via WikiLeaks.
Manning, who twice attempted to commit suicide during her incarceration at Fort Leavenworth, was the unlikely source of disclosures that rocked the United States government. However, the transgender army private later apologized for "hurting the US", claiming that she was under the wrong impression that by leaking documents in WikiLeaks she could "change the world for the better". The day after her sentencing, Manning confirmed through her lawyer that she identifies as a woman.
Earlier in the day, Chelsea had posted a photo of her "first steps of freedom", showing her Converse sneakers mid-step. Chelsea Manning, the transgender woman incarcerated for the past seven years for leaking confidential documents.
The decision angered national security experts who say Manning put U.S. lives at risk, but it won praise from transgender advocates who have embraced her transition to a female gender identity.
An online campaign set up by her attorney has raised $150,000 (£115,725) to pay for her living expenses for the first year after her release.
Manning, 29, was sentenced to 35 years in prison for leaking hundreds of thousands of secret government files to Wikileaks.
But, in January this year, former US President Barack Obama commuted her sentence in one of his last acts in the White House.More news: Mass. unemployment inched up in April
But that doesn't mean Manning isn't sorry for her actions. While in military prison, she reportedly received gender-supporting treatment.
Obama also noted that, unlike Edward Snowden, Manning had faced trial and expressed contrition for what she had done.
Pulse Films announced Wednesday at the Cannes Film Festival in France that Manning would be the focus of a documentary titled "XY Chelsea" and that she had granted filmmakers "unprecedented access".
She has reportedly tried to commit suicide twice past year and spent time in solitary confinement as punishment at the military prison in Fort Leavenworth.
Manning was convicted under the Espionage Act, a World War I era law that was meant to stop people from supporting enemies of the USA during wartime. Even though she was cleared of the more serious offense of aiding the enemy, Manning was sentenced to 35 years in prison for numerous charges under the Espionage Act.
"As I rebuild my life, I remind myself not to relive the past", the statement said.
"I take full and complete responsibility for my decision to disclose these materials to the public".
