Ask HN: Any (ex) US Consulate officers on HN?

I run a US non-immigrant community portal that has over 300K monthly visits. I sense there is a bigger opportunity to collaborate with the US consulate officer. I've tried LinkedIn, searching gov records, et al to contact ex-consulate officers. As a last attempt, want to give it a try here.

Any help with leads (forums/groups/websites) on where I can find them is really appreciated. If you (or your network) are an ex-US consulate officer, kindly drop an email to saradhi@extracttable.com. TIA.
