Help me understand something.

The government says
>Do not make hiring, firing, or recruiting decisions based on citizenship, immigration status, or national origin.
But
>If a position may require an export license to access certain items or data, employers can condition an offer on the ability to secure a license from DDTC or BIS, if one is required, but should ensure that conditions and requirements are no broader than these requirements.

If the licenses are limited to US citizens, why the fuck can't you just cut to the fucking chase and make the the requirement in the actual job posting?
