Mr. Obama's executive order defers deportations for people who came to the USA undocumented as children. "I have to be one of those people that have to speak up for these young men and young women that want to make that American dream come true", said Lopez.
Trump had campaigned against DACA and vowed to end Obama-era program if elected but has so far not made any decision about it.
This DACA program protected some young people from getting deported, but with this potential change looming, some are afraid, while others are pledging to fight.

Across the country, undocumented immigrants and their allies are taking to the streets to protest President Donald Trump's decision to phase out protections from deportation for almost 800,000 young immigrants known as Dreamers. More than 17,000 of the young immigrants benefiting from the program live in Washington state, the Democratic governor said.

Kevin Cramer, a consistent Trump supporter, expects the president's remarks to be similar to those he made in Missouri a week ago. Also joining the president were Republican Sen. "I'm optimistic about it because this is something we have to get done".

Sen. Orrin Hatch, R-Utah, has announced plans to push for "meaningful immigration reform" in Congress that provides "a workable path forward for the Dreamer population".
That means as many as 800,000 immigrants will find out by Tuesday if the Trump Administration will honor the promises of the past White House, or not.
The DACA announcement has been met with mixed responses from Trump's party.
"I have always believed DACA was a presidential overreach", Graham, a South Carolina Republican, said in a statement.
