JACKSONVILLE, Florida (CNN) -- Eduardo Gonzalez, a petty officer second class with the U.S. Navy, is about to be deployed overseas for a third time. Making his deployment even tougher is the fact his wife may not be around when he comes back. 

Mildred and Eduardo Gonzalez worry about what would happen to their family if she is deported. 

His wife faces deportation to Guatemala -- her home country that she hasn't seen since 1989. He also doesn't know what would happen to his young son, Eduardo Jr., if that happens. 

"I like being in uniform and serving my country, but if she goes back I'm going to have to give it all up and just get out and take care of my son and get a job," he said. 

"Defending the country that's trying to kick my family out is a thought that always runs through my mind." 

Gonzalez, who works on helicopters that bring cargo, supplies and military personnel in and out of Iraq, testified before a House Judiciary Committee panel last month, detailing his situation and urging officials to consider some sort of policy to deal with cases like his, where military members' families could be deported while they're defending their country overseas.

"I want to serve my country 100 percent. But with this issue in the back of my mind, I feel I can't do that," he testified on September 6. 

The U.S. military does not have a policy to deal with such cases. Each is handled case-by-case, not by the military, but by immigration authorities. The government doesn't have numbers on how many military members are in predicaments similar to Gonzalez's.
