The fortunes of an unauthorized immigrant are quite different in Texas, Tennessee and Georgia with the mere act of driving can result in an arrest and deportation, then in California, Chicago and New York where immigrants can be arrested for a variety of crimes and still not be taken into ICE custody.
This from a Migration Policy report, including the following:
The machinery of interior enforcement that had been dialed down during the final Obama years has been revved up by the Trump administration. ICE officers say that widening enforcement and ending prosecution discretion requirements have given ICE the leeway necessary to properly do which job.
The vast majority of arrests and removals (over 70%) arise from arresting persons who are already in local custody, under the 287(g) program. These actions are increasing significantly in cooperating jurisdictions, while the share of deportations due to criminal convictions is declining.
The most important constraint on increasing arrests lies in the limits of ICE cooperation imposed by growing numbers of states and localities that have large foreign-born populations. Transfer of arrested persons to ICE are below historic peaks due to lack of cooperation, for instance by law enforcement in California.
The character and unpredictability of ICE enforcement have generated an overarching climate of fear which is itself serving as an enforcement tool.
Networks of community based actors are responding and successfully providing legal services, know-your-rights, counselling, monitoring, rapid response assistance, and political advocacy in the opposition to iCE enforcement
