Does the immigration plan signed between Mexico and the United States work?

The Foreign Minister of Mexico, Marcelo Ebrard, said Tuesday that the immigration measures adopted by the country have not only worked, but are permanent and irreversible. These statements were made within the framework of scheduled meetings with US authorities, which, according to Ebrard, passed cordially and amicably. Is the plan really working? Has the crisis been alleviated? For the international analyst Ana María Salazar, the crisis on the border between Mexico and the United States continues.
