Comments:This phrase means that 'the legal process (of adoption) is fully completed and the law accords the adopted child all of the rights of a natural born, legitimate child' (MH). USCIS provides us with 'adopción plena y final' (https://www.uscis.gov/es/adopciones/inmigracion-por-medio-de-la-adopcion/otras-instancias-de-inmigracion-por-adopcion), and the Mexican Embassy gives us 'adopción plena': https://mx.usembassy.gov/es/visas-es/adopciones/ While international adoption is governed by various agreements -- the Hague convention of 1993, the UN Convention on the Rights of the Child -- neither of those texts refer to 'full and final' adoption.
