Every country would have its own minimum requirement, depending as well on the time period that you are going to stay. Therefore, I suggest that you call the embassy or check their website for any corresponding info about this. In my experience with Schengen Visas, for example, most of the member countries would need you to show that you have EUR 50 (Php 2,500+) per day of your stay. This is the bare minimum, that’s why I suggest that you add way more money to it. In line with this, be wary of providing bank statements from a bank account that is obviously new and just recently ‘fed’ with money. There is such a thing called ADB or Average Daily Balance or something equivalent to a balance history in bank statements or certificates, and that will surely indicate the state of your bank account (which most embassies might assume is not really your money and something that you might have just borrowed to prove a false financial standing).
