Instead of having it at NASA, can't they just have it at the local Holiday Inn?
Those were my thoughts, too, but it looks like the legislation has been corrected (or at least "clarified"), as it was, apparently, not intended to be used that way.

Wolf said NASA officials may have believed that the move was needed because of extra temporary restrictions on foreign nationals after a potential security breach by a Chinese citizen at a NASA facility in Virginia earlier this year.
"I have ordered a moratorium on granting any new access to NASA facilities to individuals from specific designated countries, specifically China, Burma, Eritrea, Iran, North Korea, Saudi Arabia, Sudan and Uzbekistan."
I'm not going to lie, our "rivalry" with China kind of worries me sometimes. I wasn't around for the Cold War really, but it seems like we're heading for a second Cold War if we continue to restrict, contradict, spy on and threaten each other. It is undeniable that China is on the rise. They have a quarter of the worlds population. I don't want to start the first half of the century being hated by the Chinese (and everybody else for that matter).
