My other Polish friends has just said that he stands no chance unless he has got loads of money - anyone know anything about the situation??
Tell him to talk a lot on the interview about how he loves his polish job, family, gf who lives in Poland (it's not bad to say they're going to get married), how he loves his country and how peaceful he is. That should work...
I've got american visas for three times already. Take into consideration that I'm Russian also... For Ukranians, Georgians as for the regions of the US influence there're no problems at all... just show them your passport. I believe same should be for Poles.
