It makes sense to stop poaching talented scientists and instead let them continue working for your adversaries? I don't understand how this improves national security. The proposed rule is actually worse than this:

> The changes are part of proposed rules aimed at increasing security that would limit, to 3 years, the maximum length of time visiting international researchers can work at NIST.

If researchers know that they cannot stay in the US permanently and will be forced to return to their home country in a few years, it guarantees that they must maintain ties to that home country and dramatically increases their incentive to spy. What would you do if your government asked you to spy during a temporary stay abroad, and threatened you with arrest upon your return if you refuse?
