美国开始彻底的移民改革
Undocumented immigrants are applying for the temporary right to live and work openly in the US, as a sweeping immigration policy reform takes effect.
一场彻底的移民政策改革正在美国生效，非法入境的移民纷纷申请在美国公开生活、工作的临时权力。
Up to 1.7 million people could be eligible for the programme, unveiled in June by President Barack Obama amid pressure from Hispanic（西班牙的） voters.
Republicans say Mr Obama has passed over Congress - and unemployed US citizens - with the programme.
The Latino vote could be important in November's presidential election.
Most of the estimated 11.5 million undocumented immigrants in the US are from Latin America.
'Tapping talent'
Illegal immigrants are getting their records in order as the Department of Homeland Security (DHS) starts accepting applications for the programme, which would allow them to remain and work for at least two years.
Long queues of migrants wanting to submit applications were seen outside immigration offices in parts of the US with large minority populations, such as the states of California and Texas.
In an internal document, DHS officials estimated 1.04 million people would apply in the first year.
The Migration Policy Institute and the Pew Hispanic Center have estimated as many as 1.7 million people could be eligible under the programme.
The administration's plan is to stop deporting many illegal immigrants who were brought to the US as children.
To be eligible, immigrants must prove they arrived in the US before they turned 16, are 30 or younger, have been living here at least five years and are in school or graduated or served in the military.
They also cannot have been convicted of certain crimes.
The measure has echoes of the so-called Dream Act, which offered permanent residency to young undocumented immigrants, but failed to pass after years of congressional stalemate.
"Childhood arrivals who meet the guidelines and whose cases are deferred will now be able to live without fear of removal, and be able to more fully contribute their talents to our great nation," said Alejandro Mayorkas, head of US Citizenship and Immigration Services.
