Well thats a rule I don't never understand... That's why I haven't ever applied visa because been thankful from my profiting funds. I can live with my interests, but not anymore if I sell them (and pay taxes) and move them to bank account.

It's not gambling when you are smart.

But is it allowed to move them back to stocks/funds from bank account when the DTV is approved?

So even if you have over 0 USD on stocks (where they make over 20% profit/year), they doesn't count? They have to be on bank account where they lose their value every month?

Following. I have income from savings, benefits and stocks but they doesn't count
