I go to school in the US...
It's really not that hard unless you make it hard on yourself. Never let it get to you that "oh he's not being my friend just because I have a dhari or turban".Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/sikh-youth/2675-query-for-sikhs-living-usa-canada.html
Frankly, I have more gore friends that most indians, and I'm more appreciated by other races and cultures than the average indian or Fob that comes ot America and the first thing they do is cut their hair.
Trust me, you already know how to speak english, you'll be ok, and watch you'll gain more friends than Fobs ever could. Your probably down with western culture more than the fobs are. Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=2675
Kids that come straight from India, have a bit more trouble, but they make it out to seem much harder than it is.
I play basketball with a pugh and dhari, I listen to hip hop, all my friends know what a Sikh is, and the differnece between a Sikh and hindu/muslim, and I also do bhangra.
Don't worry about it, you will make friends, whether they be hindus, muslims, goray, or kalay.
You will face racism, but tell me where you won't? Racism in America, but Sardar jokes thrown at your face in India...
And as far as them making you feel like a stranger, they may ask you questions about your appearance, but don't take it as an insult immediately or that they are singling you out...most likely, there just curious. Just explain, and they should move on.
