I am currently a green card holder and I also have an approved, still valid I-131 travel visa.   I’m studying outside the US and I usually reside in Southern California, but my family is asking me to visit Hawaii for my mother’s wedding. If I fly to Hawaii in May 2018 will they take my I-131 travel visa although it doesn’t expire til 2019? I would like to go to the wedding but then return abroad without having my visa taken.    Will I have to forfeit my visa if I go to Hawaii
