Am looking for someone to sponsor my trip?

Am an orphan living in kenya,female aged 23.all my life i have struggled in this country and the situation isnt getting any better,no opportunities for the poor like us.i would really like to relocate to usa to look for better future but financing my trip is the problem,if there is someone or a family out there in usa to help i would really appreciate. I can even work for them after relocating to repay the kindness.thanks to you all
