An earlier version of this report incorrectly stated that Arizona had received a response to its request for National Guard troops. However, the White House said it has not decided where along the southwest border the troops will be deployed. NBC DFW regrets the error.
National Guard troops will be headed to the U.S.-Mexico border, but Texas is still waiting for an official answer to its request for help.
President Barack Obama has agreed to send 1,200 National Guard troops to the U.S. border with Mexico. The White House said it has not decided where along the Southwest border, which includes parts of California, Arizona, New Mexico and Texas, the troops will be deployed.
Gov. Rick Perry has sent letters to Obama, Defense Secretary Robert Gates and Department of Homeland Security Secretary Janet Napolitano requesting National Guard troops for the Texas-Mexico border.
Almost a year and a half after the first letter was sent, Perry hasn't received an answer.
"We've not received approval (or denial) regarding Gov. Perry's request," said Perry's spokeswoman, Katherine Cesinger, in an e-mail. "But we remain hopeful that the federal government will provide the resources we've requested, including 1,000 Title 32 National Guardsmen, to secure the Texas-Mexico border."
A spokesperson at the Department of Defense said he couldn't give more information on the status of Perry's request.
