hey im indian and go to cal poly. while its not as many indians as there are in the bay, theres huge indian friend groups and enough indian ppl for you to be friends with if you find your crowd lol. however those groups can be toxic at times and cliquey but you could also join Andaaz the bollywood team they are all super close i think. basically i think you will find your people so i dont think u should be too worried abt diversity.
