My grand mother had filed an application for green card for my parents and my mother applied for a visitor visa sometime later but she was rejected. I am here in US and am a green card holder by adoption. My mother was told that since I got permanent here, they suspected that my mother will also try to settle here and so, rejected her visitor visa application. I will complete my 5 years of green card in Feb 2013 but I want my mother to visit me now since I am getting married. Will it affect her current green card application if she tries to apply for a visitor visa again and gets rejected? Also, I will be upgrading her application to immediate relative once I get my own citizenship, will it then be a problem if she has visitor visa rejections?
