US President-elect Donald Trump on Sunday reiterated his pre-election commitment to impose a stricter immigration regime, saying he will ensure immediate deportation of two to three million undocumented immigrants.

In his first extensive interview since victory at the election, Trump told CBS News that his government's primary focus would be "the people that are criminal and have criminal records, gang members, drug dealers... We are getting them out of our country or we are going to incarcerate" them. However, Trump's statement is at variance from House Speaker and top Republican leader Paul Ryan, who has said that despite Trump's campaign rhetoric, lawmakers are not prepared to form a deportation force to round up and deport undocumented immigrants.

There are an estimated 11 million documented immigrants in the country, out of which several hundred thousand are believed to be Indian-Americans. In 2014, close to 200,000 undocumented immigrants convicted of committing crimes were deported back to their countries.

Trump also told CBS News said that he will build the wall along the US-Mexico border that was a vital part of his presidential campaign. However, Trump stipulated that the wall- instead of being 'big and beautiful' like he repeatedly vowed- could end up being part-wall and 'some fencing'.

If implemented, it will not be the first instance of deportation of undocumented immigrants from the United States. Deportation of illegal undocumented immigrants from the United States to their country of origin has taken place is the past and is not a completely new concept.
