Pandemic-related public health and travel restrictions [hyperlink] were established on March 21, 2020, by the Centers for Disease Control and Prevention (CDC) and CBP [hyperlink]. Limited capacity in CBP holding facilities presents logistical and health safety challenges for migrant processing as CBP implements protocols to reduce the spread of COVID-19."
