The asylum bid is the first known case involving a Turkish military officer in the United States as Turkey purges military ranks after mutinous soldiers commandeered fighter jets, helicopters and tanks in an unsuccessful attempt to oust President Tayyip Erdogan.
The case has the potential to further strain ties between the United States and Turkey, which is already demanding Washington hand over a U.S.-based Turkish cleric it alleges was responsible for the failed coup.
The two U.S. officials, who spoke to Reuters on condition of anonymity, said the Turkish officer was working at the headquarters of NATO's Allied Command Transformation, located in Norfolk, Virginia. They did not name him or offer his rank.
However, an official at Turkey's embassy in Washington said Turkish Navy Rear Admiral Mustafa Ugurlu had failed to report to authorities after Turkey issued a detention order for him last month.
"On July 22, on that day he left his badges and his ID at the base and after that no one has heard anything from him," the official said, also speaking on condition of anonymity.
The Turkish official said he was unaware of a subsequent asylum request. An April news article on the NATO website identified Ugurlu as the Norfolk-based command's assistant chief of staff for command and control, deployability and sustainability.
The Turkish official said two other lower-level officers had also been called back from the United States to Turkey.
"But there's no detention order for them," the official said. "One of them has gone back, and the other will go back shortly."

There are concerns within the Turkish opposition that the restructuring lacks parliamentary oversight and is going too far.
Pentagon spokesman Captain Jeff Davis declined comment, referring questions about Turkish military personnel to Turkey.
