"Come out of the shadows and get right with the law," urged President Barack Obama in a televised address.
Republicans say the action, without Congress, is beyond his authority and relations will now be poisoned.
There are about 11 million illegal immigrants in the US and this year children coming across the border prompted a crisis.
Most of those affected by Mr Obama's action are the parents of children who are US citizens or legal residents.
The BBC reports that the president told the nation that what he is proposing is not amnesty.
"What I'm describing is accountability - a commonsense, middle ground approach," he said.
Although the plan will allow millions to work, it will not offer a path to citizenship or entitle them to the same benefits as Americans, he said.
"If you're a criminal, you'll be deported. If you plan to enter the US illegally, your chances of getting caught and sent back just went up."
He pledged to crack down on illegal immigration at the border and require certain undocumented migrants to pass a criminal background check and pay taxes in order to register to stay temporarily in the US.
Mr Obama said deportations would now focus on "felons not families, criminals not children, gang members, not a mother trying to provide for her kids".
More details include:
- expanding eligibility requirements for those already subject to deportation deferment because they were brought to the US as children
- ensuring undocumented parents of US citizens or legal permanent residents can temporarily escape deportation
- shifting additional resources to the US-Mexico border to increase the likelihood of apprehending illegal crossers
- streamlining the immigration court process to address the backlog of pending cases
- directing government enforcement activities to national security threats, serious criminals and recent border crossers as highest priorities for removal from the US.
Overall, the action could lift the threat of deportation for up to five million undocumented migrants.
