Let me guess, you're a #NoMyPresident kind of girl?

No they haven't, because the US Department of State and the OFAC has no clue either what is actually going to happen. The best they can do is issue an update about what they think might happen.

The Treasury is the regulatory body. They make the rules.

I use the term bullshit because that's exactly what Trump spewed on June 17th when he claimed he was, and I quote: "Effective immediately, I am cancelling the last administration's completely one sided deal with Cuba."

Here is the full statement (it was the 16th, not the 17th: https://www.whitehouse.gov/the-press-office/2017/06/16/remarks-president-trump-policy-united-states-towards-cuba

That did not happen of course, it was just more bullshit/lies to play to the audience and his fan base.

But these did happen from the order: The new policy channels economic activities away from the Cuban military monopoly, Grupo de Administración Empresarial (GAESA), including most travel-related transactions, while allowing American individuals and entities to develop economic ties to the private, small business sector in Cuba. The new policy makes clear that the primary obstacle to the Cuban people’s prosperity and economic freedom is the Cuban military’s practice of controlling virtually every profitable sector of the economy. President Trump’s policy changes will encourage American commerce with free Cuban businesses and pressure the Cuban government to allow the Cuban people to expand the private sector. The policy enhances travel restrictions to better enforce the statutory ban on United States tourism to Cuba. Among other changes, travel for non-academic educational purposes will be limited to group travel. The self-directed, individual travel permitted by the Obama administration will be prohibited. Cuban-Americans will be able to continue to visit their family in Cuba and send them remittances. The policy reaffirms the United States statutory embargo of Cuba and opposes calls in the United Nations and other international forums for its termination. The policy also mandates regular reporting on Cuba’s progress—if any—toward greater political and economic freedom. The policy clarifies that any further improvements in the United States-Cuba relationship will depend entirely on the Cuban government’s willingness to improve the lives of the Cuban people, including through promoting the rule of law, respecting human rights, and taking concrete steps to foster political and economic freedoms. The policy memorandum directs the Treasury and Commerce Departments to begin the process of issuing new regulations within 30 days. The policy changes will not take effect until those Departments have finalized their new regulations, a process that may take several months. The Treasury Department has issued Q&As that provide additional detail on the impact of the policy changes on American travelers and businesses.

It's not a clusterfuck. It's a process, one you don't understand, and you're more speaking out of emotion and less out of what was signed.
