Can I apply for a Thai visa at a consulate in Taiwan if my application is pending in the US?

Hello friends,

I applied for DTV as remote worker at LA consulate mid March and around 10 days later got a request for more documentation. It’s been more than 30+ days now after submission with no update. I emailed them already 3 weeks post re-submission and still no update on the application. Still says ‘pending document check.’ If I get accepted, great. But, if I get rejected, can I walk into a consulate in Taiwan and apply there as a US citizen? It’s unfortunate that the LA consulate has taken as long as it has because I’ve heard from others that the Thai consulates in other parts of the US are processing at a much faster rate. Any advice will be appreciated.
