Watch President Obama's Speech On Immigration Reform 2014
On November, 20, the United States President Barack Obama enforced immigration overhaul.
Millions of immigrants living illegally in every state in the US will be allowed to apply for work permits under a major shake-up unveiled by President Barack Obama.
This applies to immigrants who have been in the US for five years and have children staying legally in the US.
About four million people are expected to benefit from a reform package forced through using executive orders, which allow Mr Obama to bypass Congress.
Republicans have accused the president of an "illegal power-grab".
There are estimated to be 11 million illegal immigrants in the US.
