On September 5, 2017, President Donald Trump had a tough call to make. He made the “tough decision” to revoke DACA, an executive action put into place under Obama’s order. This program provided relief and opportunities to 800,000 “Dreamers,” undocumented immigrants who were illegally brought into the country as children.

My own sister, a hard working immigrant who has never committed a crime, who relies on DACA to give her the chance to work here legally so she can give herself a good education and support her family, will be heavily affected by Trump’s decision. Something as simple as getting an education and a job, which most American citizens view as an obligation from their country, is a treasure for her. This cruel decision has threw her world, and many others, into one of uncertainty.

When my family and I heard about Trump’s decision to rescind DACA, we were furious. But more than that, though, we were scared. DACA has helped innocent children who are not harmful to their country, who are trying to improve the United States. DACA has helped my sister in a world where if you weren’t born on this piece of land, you were considered an “alien.” Rescinding it is now stealing from 800,000 futures.

This decision has felt like a crushing weight on my chest, but to my sister, it felt like her whole world had been crushed.

I never let myself wander near the idea that someone very close to me can be deported and I would never see them again, because I never took Trump’s tweets seriously. But now I’m face to face with the realization that this is a serious threat and my sister may be ripped away in six short months from the only home she’s ever known.

“The fact that the leader of our free country can go back on an order that was institutionalized to help teens/young adults make a name for themselves in a world where we’re deemed inferior, a country that makes us feel like we don’t belong, even though it’s the only home we know, is astonishing to me,” said Youssra Ismail, my sister. “I don’t know what will happen, but I do know that whatever the outcome is, we must remain positive. We cannot dwell on negatives or let this discourage us. This decision was cruel, but it’s only making me push harder, and strive for better. Because at the end of the day, the U.S. is home to us 800,000 dreamers just as much as it is home to the ones who were fortunate enough to be born on this side of the border.”

Later on in the night, Trump had tweeted that if Congress hadn’t legalized DACA in the next six months he would “revisit it.” But by saying this he went back on his words that he had spoken just moments before. I don’t know if Trump is a liar, or just can’t make up his mind, but I do know that his decisions can inflict damage on his country. Trump cannot be underestimated.
