Biden’s Border Problem, and How to Fix It The U.S.-Mexico border wall in Nogales, Arizona. (Ignatian Solidarity Network, https://tinyurl.com/ynfpzyv3; CC BY-NC 2.0, https://creativecommons.org/licenses/by-nc/2.0/) President Biden has a border problem. The U.S. is seeing a deeply troubling increase both in total unaccompanied children (UACs) and in very young UACs—children as young as six or seven years old. The current problems at the border have both short- and long-term causes. In the short term, the Biden administration contributed to the problem with two related steps. First, it chose to continue the Title 42 coronavirus border restrictions that severely limit family entry. Second, it chose to exempt UACs from Title 42. In the longer term, addressing the exponential increase in both UACs and immigrant families over the past 10-12 years will require action by Congress and the courts. This post addresses both short- and long-term issues, centering on UACs and families.
