Giving Compass' Take:

· Although the First Step Act is set to release 3,000 federal prisoners come mid-July, The Marshall Project explains that it has a much different impact for 750 non-citizen prisoners.

· How has the population of the federal prison system changed over the past few years? 

· Here's more on the First Step Act and what it means for criminal justice.

President Trump convened a news conference last week to celebrate the release of 3,000 federal prisoners on July 19 as part of the First Step Act. But not all of those inmates will actually walk free: 750 non-citizens could well face deportation.

It is one more example of the inflated hopes and modest reality of the First Step Act, which eases sentences for drug convictions, improves prison conditions and creates more job-skills training programs—but only in the federal system, which accounts for less than 10 percent of those incarcerated.

The 750 non-citizens released from federal prisons will be held for transfer to Immigration and Customs Enforcement custody so ICE can start the deportation process, according to the Bureau of Prisons.

While the Trump administration has pressed to increase deportations, there is ample precedent for non-citizens being released from prison, only to be ejected from the country. In 2015, during the Obama administration, more than 6,000 prisoners were released after the nonpartisan U.S. Sentencing Commission revised sentencing guidelines for some drug crimes. More than 20 percent of those released were sent to ICE to face deportation.
