Congressional Budget Office Cost Estimate: Statutory Pay-As-You-Go Effects of Rules Committee Print 116-27, the Homeland Security Improvement Act of 2019, as Reported by the House Committee on Homeland Security, with Modifications [open pdf - 21KB]
From the Document: "Rules Committee Print 116-27, a modified version of the text of H.R. 2203, as reported by the House Committee on Homeland Security, would make several changes to immigration policy and to the operations and oversight of the Department of Homeland Security (DHS). Among those changes, section 208 of the bill would terminate DHS's Migrant Protection Protocols (MPP) and U.S. Customs and Border Protection's policy of limiting the number of prospective asylum applicants who may cross the international border based on the space available at the port of entry (known as metering). Ending MPP and metering would allow more aliens (non-U.S. nationals) who have expressed a fear of returning to their country of nationality to enter the United States while awaiting removal proceedings before an immigration judge. It is at such proceedings that affected aliens have the opportunity to seek relief from removal."
