The United States and Cuba relationship throughout the years has been cold, but now things are changing. The U.S. State Department provided more information about the its embassy in Havana.

Based on a Fact Sheet from the State Department, the U.S. embassy "will operate like other embassies in restrictive societies around the world, and will operate in sync with our values and [President Barack Obama's] policy." The Department noted its embassy will allow the U.S. to be more effective in promoting U.S. interests, values and engagement with the Cuban population.

"Diplomats will be able to meet and exchange opinions with both government and nongovernment entities," the State Department added. "Chief of Mission Jeffrey DeLaurentis will be the senior-most official in the new embassy and will serve as Charge d'Affaires ad interim. Normalizing relations is a long, complex process that will require continued interaction and dialogue between our two governments, based on mutual respect."

Obama announced the reestablishment of diplomatic relations with Cuba last December, and he said this will "help the promotion and encouragement of respect for human rights and fundamental freedoms for all."

CNN reported this will be the first time in 50 years the two countries are opening their embassies, which is scheduled to open on July 20.

"When the United States shuttered our embassy in 1961, I don't think anyone thought it would be more than half a century before it reopened," President Obama said.

Cuban President Raul Castro sent a letter to Obama about resolving their differences. He read the letter via state run TV, "We want to develop a friendship between our two nations that is based on the equality of rights and the people's free will."

The Cuban Foreign Ministry indicated there are still hurdles to overcome in the U.S. and Cuba relations because of the embargo the U.S. imposed on Cuba. The embargo in Cuba has been in effect since 1961. The embargo limits American businesses from conducting business with Cuban interests. Since January, the embargo was relaxed a little with the United States lifting the ban of direct flights to Cuba.

Many Latino politicians weren't too excited about the policy announcement. Sen. Marco Rubio, R-Fla., has been an opponent of the renewed diplomatic relations.

"I intend to oppose the confirmation of an ambassador to Cuba until these issues are addressed," Rubio said. "It is time for our unilateral concessions to this odious regime to end."

Sen. Ted Cruz, R-Texas, said Obama "surrendered" to the Castro administration. Cruz also said he will block any nominee for Cuban ambassador and will not contribute any funds to the U.S. Embassy in Havana.
