WASHINGTON, Nov 5 (Reuters) - U.S. Immigration and

Customs Enforcement aims to open a call center that would have a

dedicated unit to track down unaccompanied migrant children with

the help of state and local police, an agency contracting

document said, part of a wider Trump administration effort to

find and potentially deport the minors.

The center would aim to feed information from state and

local police to federal authorities, including the locations of

unaccompanied children, according to the document, which was

posted to a government contracting website on Tuesday. ICE wants

to create a round-the-clock facility that could handle

6,000-7,000 calls per day related to immigration enforcement, it

said.

President Donald Trump's administration kicked off an

initiative in February to find and deport unaccompanied

children, an unprecedented push to track down minors who crossed

the U.S.-Mexico border illegally without a parent or guardian.

The Trump administration has since taken other steps to

increase enforcement, including an attempt to deport dozens of

Guatemalan children despite them having active U.S. immigration

cases.

At the same time, the Republican administration has greatly

expanded partnerships with state and local authorities to ramp

up immigration arrests under a program known as 287(g). The

number of state and local agencies participating in the program

has risen from 135 just before Trump took office to more than

1,100, according to ICE data.

Critics have said the partnerships can erode trust in

immigrant communities and make people less likely to report

crimes.

The contracting document said the call center would be

located in Nashville, but did not explain why that city was

selected. CoreCivic ( CXW ), one of the main companies that contracts

with ICE to operate immigration detention centers, is

headquartered in Nashville.

The U.S. Department of Homeland Security, ICE and CoreCivic ( CXW )

did not immediately respond to requests for comment.
