hi mavid.
i showed 6 mos bank statements, its not important how much that u hv loads of money left on that statement everyday..what is important is that there is movement of coming in and out on it,,to show theres income coming in...and normal that if theres income theres expenses lol..so theres no problem on the amount showed on it...as long as existing and moving...bt i produced also bank certification that i hv savings containing an amount that the eco will think can support my stay for at least one month as wehat i said on my application but i stayed more than i said really lol..i also submit certified copy of business permit and some land tittles...ITR too latest... and the sponsor letter..i think its important that theres an address that u will show where ur going to...so invitation letter is so important too...
