SUGGESTION PLEASE

Hello, i am new here. i however have a visa experience. i was supposed to travel with my parents to attend my immediate elder brother's wedding in Chicago  though the appointment was booked together, they would not allow us take it together. my parents took it together while i took mine separately. the officer, a black young lady asked me what my visit was for, i told her i am attending my brother's wedding and i am the best man. she asked what i do, i told her i am a lawyer. again ow much i earn, i told her, about N220,000. she then worked at her computer and suddenly asked me why the wedding is taking place in Atlanta while the couple stay in Chicago  Actually my brother is taking his PhD in Chicago and they lived and met in Chicago but they are more comfortable with Atlanta because the bride family previously lived there. more so  its a destination wedding and people coming all around the world for it. she wasn't convinced. she asked if i have made plans for the trip and i said i have a reservation at the Sheraton in Atlanta where the wedding will take place. she just did not request for any of my documents. she asked if married, i said i had a fiancee. out of the country before, i said no. she then says am not qualified for a visa. i was so distraught. my brother was devastated  only my parents were given. i wanted to appeal it but i dropped it. i think they assume i do not have enough ties. they don't care how important what you are going to do in the US is, once ties is not well established, they take you down. then i ll probably travel around to some places before applying again  anything to show the circumstances have changed. any other suggestion please?
