The current legal limbo for undocumented immigrants carries immense social costs, not only for the immigrants themselves but for their families as well. Undocumented immigrant families are at the mercy of prevailing political winds, and the Trump administration has not been kind to them.
Over the past few years, for example, it has become almost a common occurrence for a US-born child (who the Constitution grants automatic US citizenship) to suffer the deportation of at least one of their parents. This state of affairs puts these US citizen children into a difficult dilemma — return to a homeland they have never been to (and may not speak the language of) or stay in the US without one or even both parents.
Not only the children but also the US citizen or permanent resident spouses and partners of deported undocumented immigrants suffer from depression, poverty, and other social and psychological problems. Humanitarian concerns alone dictate that something must be done.
