As Henning pointed out in his comment, for the second question your monthly flow of income and expenditure are important. If USD 10,000 or even more simply show up in your account, that does not help. If you can save a few hundred USD each month from your well-documented income, much less than USD 10,000 should be enough. That's because it is credible that a young man would save the disposable income for a couple of months and then go on a holiday trip, that's what young people do.
