Hundreds of thousands of people who were brought to the US as undocumented children are breathing a collective sigh of relief after the US Supreme Court rejected President Donald Trump's efforts to revoke the program protecting them from deportation.
Almost 700,000 migrants known as 'Dreamers' were protected by the Deferred Action for Childhood Arrivals (DACA) program, which was introduced by then-president Barack Obama in 2012.
The program allowed Dreamers to live, work and study in the US under special authorisation that could be renewed every two years.
What did the court decide?
Mr Trump rescinded the program in September 2017, leaving Dreamers in limbo for almost three years as his decision was challenged in the courts.
The legal case looked at whether Mr Trump followed proper government procedure when he rescinded DACA in 2017.
On Thursday, the Supreme Court found the president had not done so, with five of the nine judges deeming his move to end the program unlawful.
Chief Justice John Roberts, a conservative, sided with the court's four liberal judges and found Mr Trump's move to rescind DACA was "arbitrary and capricious" under law.
"We do not decide whether DACA or its rescission are sound policies," Chief Justice Roberts said.
"We address only whether the agency complied with the procedural requirement that it provide a reasoned explanation for its action," Justice Roberts wrote.
The court's decision followed years of lobbying by Dreamers and their supporters.
Martinez Rosas, who moved to the United States from Hidalgo, Mexico at an early age and lived in Texas as an undocumented immigrant, was at the Supreme Court when the decision was handed down.
She is now the deputy executive director of United We Dream, an immigrant youth advocacy group.
"I'm elated. I am really affirmed that the movement of young people organising 11 million undocumented people demanding exactly what we deserve, we win," she said.
"And so I'm honoured to be here today at the Supreme Court and ready to keep fighting for more."
What does this mean for Dreamers?
The Supreme Court's ruling means all the roughly 700,000 migrants currently enrolled in DACA will continue to be protected from deportation.
Dreamers can continue to renew their status every two years, allowing them to continue living, working and studying in the US.
However, the ruling does not mean Mr Trump cannot try to rescind DACA again.
Responding to the ruling, Luis, a 23-year-old DACA recipient who came to the US from Colombia at the age of 15, said he feared Mr Trump would try to rescind the program again if he was elected for a second term.
"It's allowed me to go to college. It's allowed me to get a full-time job. That could have all been stripped away had the court decided differently today," he said.
"However, I know that if he gets re-elected and he has more time, he can continue to try to get rid of DACA through other means that the court might approve, like he did with his immigration ban a few years ago... I'm nervous about November and the possibility of Trump being re-elected."
Most Dreamers arrived in the US as small children, with many saying they did not even know they were undocumented migrants until they were teenagers and had little connection to their home country.
How has Donald Trump responded?
Mr Trump shot off a string of tweets following the ruling, asking his followers: "Do you get the impression that the Supreme Court doesn't like me?"
"As President of the United States, I am asking for a legal solution on DACA, not a political one, consistent with the rule of law," he wrote.
"The Supreme Court is not willing to give us one, so now we have to start this process all over again."
Unhappy with the ruling, Mr Trump went on to say he would be releasing a new list of conservative Supreme Court judge nominees.
"These horrible and politically charged decisions coming out of the Supreme Court are shotgun blasts into the face of people that are proud to call themselves Republicans or conservatives," he wrote.
"We need new justices of the Supreme Court. If the radical left Democrats assume power, your second amendment, right to life, secure borders, and religious liberty, among many other things, are over and gone."
