not my rules when I wanted it live in France I had to go to Germany to become a European resident just to use the French embassy in Germany bc the one in the USA would have taken a lifetime if ever to process the visa.
most embassies especially European ones want you to apply from your passport country. It’s not my favorite thing but then if you don’t some will after a certain time like 6 months or a year
You’re supposed to apply from your home country or where you have a residence permit. It’s the sea countries that are getting scrutinized for the very reason you are posting.
If you are applying in Laos or visa run countries that aren’t you home country they are starting to ask to verify documents at the point of entry now fyi
