WASHINGTON -- Under orders from President Barack Obama to enforce immigration laws "more humanely," Homeland Security officials are focusing on at least two major policy changes that would slow the pace of deportations of immigrants in the U.S. illegally.

But the White House has tentatively rejected proposals to expand an Obama administration program to allow the parents of young people who were brought to the country illegally to stay.

Officials said Friday the changes under review would effectively stop most deportations of foreigners with no criminal convictions other than immigration violations and focus enforcement efforts instead mostly at those charged or convicted of felony crimes or who pose more of a threat to public safety.

Thousands of people are deported every year who have overstayed their visas or entered the country illegally but have broken no other laws. Many are parents of children who are U.S. citizens.

The deliberations mark a shift for the Obama administration, which has repeatedly insisted it has done all it can to make major changes in immigration policy on its own. Obama has said only the immigration legislation now stalled in the Republican-led House can fix what all sides describe as a broken system.

But a public campaign by immigration activists and lawmakers appears to have forced Obama to rethink his position. In recent days, former political allies caustically dubbed Obama the "deporter in chief" and Latino members of Congress threatened a resolution calling on him to ease the deportations.

Hoping to reunite the fraying coalition behind what may be the last major legislative effort of his presidency, Obama promised the Congressional Hispanic Caucus on Thursday that he would ask Jeh Johnson, secretary of Homeland Security, to look for changes "within the confines of the law."

White House officials said Friday the president had expressed interest in modifying policies to prevent the separation of families. His administration is on track to deport 2 million people by next month.

Peter Boogaard, spokesman for the Department of Homeland Security, said reports of specific changes under review were inaccurate. He said Johnson was taking a "hard look" at ways to "enforce our immigration laws effectively and sensibly, in line with our values."

"It is fair to say that process is ongoing and will be conducted expeditiously," he said.

Obama and his senior staff met Friday at the White House with 17 representatives of labor groups, Latino organizations and faith groups that are pushing for immigration reform. The president assured them he has "deep concern" for the pain of families separated by deportations.

"We've gotten the attention that we needed," said Rep. Lucille Roybal-Allard, D-Los Angeles.

The changes under consideration fall short of activists' preferred solution: expanding a 2012 program created by Obama that allows some young people brought to the country illegally as children to remain. Many advocates want the program -- called Deferred Action for Childhood Arrivals -- broadened to include the children's parents or other family members.

White House lawyers have considered expanding that program to include people in the country illegally who are related to a U.S. citizen and have a pending petition for permanent residency, according to one official.
