She wants to study in America and her father is telling her not to wear hijaab

I am a 21 year old muslim girl I have been wearing the hijab for the past one and a half years against the wishes of my parents. The next year insha allah I'll be moving to United States for pursuing my Higher studies. My father strongly advised me not to wear the hijab there cause people do not like to be distinguished there . I am facing a dilemma now. I strongly prefer to wear the hijab cause I was told it is sin not to wear hijab.   Could you please advise on this?

Praise be to Allaah. 

You have done well, may Allaah bless you, when you followed the laws of Allaah and put on hijaab. You should note that there is no obedience to any created being if it involves disobedience to Allaah. You have to continue to wear hijaab and follow all the other laws of sharee’ah. But we are afraid that if you go to America to study, you will face waves of fitnah from all directions, all kinds of doubts and forbidden desires. If you can study in a university or college which pays attention to the rules of sharee’ah such as wearing hijaab and avoiding mixing, then that is what you should do. May Allaah help us and you to do all that is good.
