The District Court in Washington, D.C. upheld a ruling that the program had to resume taking applications after he tried to end it.
The Justice Department wants the Supreme Court to hear the issue quickly.
Although there is a conservative majority on the Court, it's not clear if that will translate into a ruling that Trump wants.
In the meantime, raids by Immigration and Customs Enforcement (ICE) agents under Trump have risen so much that even Trump supporters are having second thoughts.
When he got his driver's license, he didn't know that the papers that got him into the country were fake, paid for by his family in the hopes of giving him a better life.
His life was great, except for the weight of the secret he carried, forcing him into a virtual closet, afraid to let anyone, except for a few trusted confidants, know him.
He has made himself a voice for the voice-less, founding the nonprofit Define American and working as an immigration-rights activist and a filmmaker, despite being left to himself by immigration authorities.
He has become an entrepreneur because he can hire others but can't hire himself.
I think I was putting my sanity at risk.
I think I risked my sense of self.
It felt like I had to create a different person to lie to my friends.
I hope that young people don't take their citizenship for granted.
I hope they realize that what was paid for it paved the way for them to be free.
That freedom is not comfortable.
Your crown has been paid for.
Your ancestors gave it up for you.
At the state and local levels, some places are resisting the Trump administration's efforts by creating sanctuary cities where local officials do not comply with the federal effort to deport undocumented workers.
Although a state was within its rights to require police officers to verify the status of people they had reason to believe were here illegally, it could not affect the federal right to set immigration policy.
The issues have not been untangled by the courts.
An immigrant from Haiti, Alix Schoelcher Idrache earned his citizenship while serving in the Maryland National Guard before being accepted into the nation's most prestigious military school.

Sanctuary, prosperity, and an improved quality of life are what non-Americans who are threatened or impoverished in their native countries seek to gain by becoming legal or undocumented immigrants.
People who are already American citizens have a stake as well.
The desire to be sensitive to humanitarian concerns, as well as to fill gaps in the nation's pool of workers and skills, and to meet the needs of current citizens is at issue.
The goals are turned into law by policymakers in Congress and the White House, and their solutions are implemented by the bureaucracy of the US Citizenship and Immigration Services.
It's not easy to make a single nation out of such a diverse group of people.
Most Americans share some fundamental attitudes and beliefs about how the world works and how it should work.
Our political culture pulls us together and provides a framework in which we can disagree politically without resorting to violence and civil war.
Values are ideals or principles that most people agree on, even if they disagree on how the value should be defined.
Values and beliefs are not descriptions of how the world should be.
Normative statements are dependent on the arguments that are made to back them up.
We take our own culture so much for granted that we aren't even aware of it, and we just think we have the correct outlook and those who live elsewhere are simply mistaken about how things should be done.
It's easier to see our own political culture compared to another's.
Some people find themselves at odds with political culture.

The legitimacy of our system was challenged during the 2016 election campaign, which showed how fragile the cultural ties that bind us can be.
In American political culture, our expectations of government have traditionally focused on rules and processes rather than on results, and we think government should guarantee a fair playing field but not guarantee equal outcomes for all the players.

Some of the major partisan divisions in American politics are due to differences on these matters, but they are more prominent in the United States.
To show this point, we can compare American culture to the more social democratic cultures of the Nordic countries.
The United States and the countries in the Nordic region are all capitalist democracies, and they all agree that individuals should make most of the decisions about their own lives.
Chapter 1 compares political and economic systems.
Americans don't agree on a lot, but they still have the right to disagree.
The government protects the most offensive speech, but most citizens don't like it.
