Obtaining an official passport at an isolated duty station
So I'm trying to get an official passport for my next duty station however I'm currently in a very remote location so we don't have passport services here. I tried submitting an application through the state department website but after they processed my 1056 form I was told I'd need to go to the embassy in Washington DC which may not be possible. I tried calling the TSC passport office in Japan yesterday but they said they're not currently available and so they referred me to an office in Yokota and also Camp Zama. I couldn't get ahold of the Yokota office but when I looked up Camp Zama's passport services it looked like it would be the same situation, where I'd need to go in person. I'm about to try requesting out to our HQ admin for TDY orders to go to Japan to handle the passport application but wanted to know if going in person is the only way to get an official passport? I tried emailing the first site I submitted my application to but they never responded.
TLDR can I do an official passport application remotely over teams or VTC, or do I have to go in person?
