President Obama is set to announce his plan for executive action on immigration reform on Friday in Las Vegas.

The president may also expand on the details of the executive action as early as tomorrow (Thursday).

Politico reports that Jeh Johnson, Secretary of Homeland Security, has confirmed that Obama will unveil his plans “in the coming days,” adding that they will be “comprehensive.”

It is believed that the announcement will take place at Del Sol High School, the same place where Obama delivered his “now is the time” charge for Congress to act on comprehensive immigration reform in January 2013.

With Senate-approved immigration legislation stymied by the Republican-led House of Representatives, the president’s plan for executive action immigration reform has been in the works for some time.

Last week, news of his impending action was leaked to the media, raising questions about what it will mean for an estimated 5 million undocumented immigrants with long term ties to the US or US citizen children. In total there are currently close to 11 million undocumented immigrants living in America.

There are as many as 50,000 undocumented Irish currently living and working in the US. Those interviewed about Obama’s plans have expressed both optimism and caution, saying “We’ve been there, done that and nothing is certain, so what’s the point of getting excited?” They are eagerly awaiting clarification as to who will be eligible under the new legislation.

The plan is widely rumored to have 10 parts, one of which concerns deportation reprieves for the undocumented. The others range from higher pay for immigration officers to increased border security.
