Hi I was wondering if someone can help me. I hear it is almost impossible for a woman from Ukraine to get a tourist Visa to the US. But I see young unmarried women in th US. I know a girl who says she can get a visa and set up a trip through a travel agency. Is this possible? Any help you can give would be great.

Thanks
