For me most awful thing in immigration that i can't marry green card holder at all. Because we need to wait 5 years abroad and she can't leave country for more than half year for conversion Green Card to citizenship and i can't came to US because i am married in permanent resident. Why, hell, i can't may woman that i love and with whom i want to make family? I am extremely skilled worker and done two businesses in my country and i wanted to make more in US.
