youre missing the point. Each case is different and what they ask from someone who is employed will be different to someone who is a self-employed trader like the OP. Or do u think hundreds of traders have applied and received from each embassy already?
when did I say nobody should ask for advice? Loads of good advice given here and havd asked myself but nobody will give a definitive answer to the OP as nobody knows where they are applying
no youre not youre asking what documents they require which will be different for most people and each embassy! Go ahead and listen to someone else’s guess on what u might need at a specific embassy if u want! Do u not think it would be best to get straight from the horses mouth?
