The Pentagon said on Thursday that military students of Saudi nationality presented no threat to the United States.
This comes after a shooting earlier this month by a Saudi Air Force officer, who killed three people at a base in Florida.
In its review of about 850 military students from Saudi Arabia studying in the United States, the Pentagon found no information indicating an immediate threat to US security.
"We can report that no information indicating an immediate threat scenario was discovered," said Garry Reid, a director for defense intelligence, briefing Pentagon reporters.
"A summary of all relevant information has been provided to the sponsoring organizations, namely the Defense Security Cooperation Agency, or DSCA, and the military departments," he added.
Following the shooting on December 6, the Pentagon ordered a broad review of vetting procedures for international students who participate in training on US military installations.
About 5,000 military students from 150 countries are receiving training in bases within the United States.
Princess Reema bint Bandar Al Saud, the Saudi ambassador to the US, visited the military air base in Pensacola, Florida last week.
She extended her condolences after the tragedy caused by the second lieutenant Saudi Mohammed Shamrani.
The ambassador met with the base commander, and reiterated her condemnation of the attack.
She stressed her readiness to provide any possible assistance to expedite the investigation.
