Perry also wants President Barack Obama and Congress to hire an additional 3,000 border patrol agents for the Texas border, which would eventually replace the temporary guard forces.
He made the announcement, which he called Operation Strong Safety, on Monday in Austin.
Perry's state has received the majority of migrant children, especially in the Rio Grande region, and he has repeatedly called on the federal government to deploy the National Guard.
"I will not stand idly by," Perry said. "The price of inaction is too high."
After a meeting with Perry and others in Texas earlier this month, Obama said he was open to the idea but would rather focus on a permanent solution to the crisis that has overwhelmed border services and triggered nationwide political fallout.
White House spokesman Josh Earnest said the White House has not yet received the formal communication required for Perry to deploy guard troops.
But he said if Perry follows through, he hopes those forces would be coordinated "with the significant ongoing efforts already in place."
The Rio Grande sector, where most of the immigrant children are turning themselves into the border patrol, has a large number of agents but it is also the largest crossing.
It currently has 3,000 border patrol agents covering 320 miles of land and 250 miles of water, which equates to 5.4 agents per mile. The Tucson sector, for instance, has approximately 15.7 agents per mile.
Both Perry and Obama have the authority to deploy National Guard troops, but whoever authorizes it has to pay for it. If Perry follows through, then Texas will have to pick up the cost.
Perry has been an outspoken proponent of securing the border since the influx of immigrants began.
The potential 2016 presidential candidate has used the issue to remake his image on immigration. His previous White House campaign was crippled partly because of a law he signed giving children of undocumented immigrants in-state college tuition.
