I once screwed up my application which was already last minute. Found an agency online that offers “expedited” visa processing, usual time is 3 business days, they did it same day for me. It was expensive ($150 USD or something) and pretty dodgy (correspondence through Whatsapp etc) but I decided to roll the dice and it worked, same day. I asked how they do it and they basically they said they have contacts in the embassy I assume they bribe lol
