President Trump's immigration enforcement plans are encountering mixed results in early implementation, with some facilities remaining underutilized while new diplomatic agreements expand deportation options.

Internal government documents reviewed by CBS News indicate that immigration detention facilities at Guantanamo Bay are operating well below capacity, despite Trump's earlier campaign promise to hold 30,000 migrants at the naval base. The facilities remain largely empty, raising questions about the feasibility of using Guantanamo as a major immigration detention center.

Meanwhile, the administration has secured a new agreement with the Dominican Republic to accept third-country migrants deported by the United States. The deal represents a reversal of position by Dominican President Luis Abinader, who had previously opposed such arrangements.

The agreement with the Dominican Republic is part of broader Trump administration efforts to identify countries willing to accept deportees who cannot be returned to their countries of origin. Such third-country agreements are considered crucial for immigration enforcement operations when migrants' home countries refuse repatriation or lack diplomatic relations with the United States.

The contrast between the underutilized Guantanamo facilities and the new Dominican agreement highlights the complex logistical and diplomatic challenges facing the administration's immigration enforcement agenda. While some promised detention capacity remains unused, diplomatic efforts to secure cooperation from regional partners continue to advance.
