Its not easy to love someone unconditionally Dude so go for it. But sometimes heart changes when you really meet the person face to face. We human have different faces. Make sure she loves you for who you are not for your Green Card.
SOmeone I knew who was in Australia a Green Card Holder was in love with this Rana girl from KTM for 3 years. They had decided to get married. Finally this guy went to KTM to meet her but he had not mentioned that he had given up Australian Green Card and his Registered Nurse job as he had earned enough in 15 years to live like a King in Nepal. Out of surprize she broke off with him after hearing he was in Nepal for good never returning to Australia. The guys was devastated. So be very careful.
