TUCSON, Arizona (KVOA) -- The University of Arizona released its study on migration and deportation.
The newly released study found 1 in 3 deported immigrants said their home is in the United States, not Mexico.
10 percent said they've been physically abused by U.S. authorities, and 30 percent said they were forced to sign immigration papers they didn't understand.
Researchers surveyed more than 1,000 deported immigrants for this report from 2010 to 2012, and they found 1 in 4 of these deportees have children under the age of 18 who are U.S. citizens.
Carol Estrada said she can't imagine being separated from her baby.
"I will do anything for my baby," said Estrada.
But according to the University of Arizona's immigration report, in many cases, mothers are separated from their young kids when they're found in the country illegally.
Estrada said she has no reason to fear deportation.
She's in the U.S. legally, but she can't say the same for some family and friends.
"They're scared to be caught because if they get caught, they'll be taken to jail," said Estrada.
