(Reuters) - More than half of U.S. citizens believe that most or all of the country's 11 million illegal immigrants should be deported, according to a Reuters/Ipsos poll released on Wednesday that highlights the difficulties facing lawmakers trying to reform the U.S. immigration system.

The online survey shows resistance to easing immigration laws despite the biggest push for reform in Congress since 2007.

Thirty percent of those polled think that most illegal immigrants, with some exceptions, should be deported, while 23 percent believe all illegal immigrants should be deported.

Only 5 percent believe all illegal immigrants should be allowed to stay in the United States legally, and 31 percent want most illegal immigrants to stay.

These results are in line with other polls in recent years, suggesting that people's views on immigration have not changed dramatically since the immigration debate reignited in Congress last month, according to Ipsos pollster Julia Clark.

"It's not Americans' views that are shifting. It is that the political climate is ripe for this discussion," after the November election when Hispanics voted overwhelmingly in favor of Democratic President Barack Obama, she said.
