As Assistant Secretary of State for Western Hemisphere Affairs under President George W. Bush, Ambassador Noriega was responsible for managing U.S. foreign policy and promoting U.S. interests in the region.

[5][6] Upon entering the private sector as a lobbyist in 2005, Noriega went to work for Miami-based law firm Tew Cardenas LLP, which, according to LD-2 reports filed in the second quarter of 2004,[7] was actively lobbying for the interests of free-market proponent organizations in Haiti.

Noriega had previously claimed that the democratically elected Zelaya posed a threat to the region because Honduras was ground zero in what he described as "the continued spread of Chavista authoritarianism under the guise of democracy".

Other lobbying activities conducted by Roger Noriega through Vision Americas include a $25,000 contract[13] in 2010 with Venezuelan firm Alodiga, claiming to "support the client's registration and regulatory issues", and a $45,000 contract[14] in 2016 with the Haitian branch of global industrial, financial, supply chain, and telecommunications giant GB Group, owned by billionaire opportunist and prospector Gilbert Bigio which specified an initiative related to "educating U.S. stakeholders about the economic opportunities of a modern port system in Haiti".

Noriega signed the Madrid Charter, a document drafted by the conservative Spanish political party Vox that describes left-wing groups as enemies of Ibero-America involved in a "criminal project" that are "under the umbrella of the Cuban regime".
