Is it possible to find a sponsor (who can work with me music producer, manager, agent etc.) for my O1-B from music conferences in America...?

Yes. But (as well as your travel / health insurance cover for the USA) you sholud always carry the prescriptions / note from your doctor confirming that they are prescribed. Although unlikely, You may want to check that all of your drugs are allowed in the USA (a few are different) Also consider... that you will be unlikely to get the same ones (or any!) prescribed while in the USA so taking your 6 months supply would be a smarter move anyway.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
