Depends on the embassy, I applied at the Washington DC embassy and deposited the money from my business checking to my personal the day I applied. Transferred it back 10 days later after I was approved.
That's why I didn't do the freelancer even though I own my own business. I just got a letter from my doctor I've been seeing in Bangkok and she wrote me a letter stating I'm a patient of hers and the hospital on official hospital letterhead. Was approved with no questions aaked.
