I'm doing the Non O, 90 day Spouse visa application now. When it comes to providing financial evidence (not earnings, just money in the bank), what period of time do they require because in the manual they just say "bank statements", nor do they state the minimum amount? For example, do you suppose that a July 2022 bank statement (one month) continuously showing approx USD200k would suffice? If not, what do they need? I googled this but didn't find anything definitive.
