totally dependent on the consulate so start going to their websites and looking at the requirements ๐
To be honest, there's no need spinning your wheels trying to find a consulate that will do it and where you meet the requirements
You're on an OA now, just exit/re-enter on a visa exempt entry. Then get the bank letter, the updated bank book, the correct documents and go apply at the immigration office for the 90 day Non-O visa. Most offices require you have 15 days or more left on your entry stamp. SO if you come in on a 30 day visa exempt you need to get your shit together and go apply pretty fast, but it's totally doable especially seeing as you've already got the funds, etc and are ready in that regard
