How is the essay overall? Is the rest of it fine?
You have facts and points, but I think you have more potential to improve its presentation. I feel that you want to tell them you love to be socialized and that's why you like NJ, which is culturally more diverse. If you improve the flow of ideas, this message would be delivered more effectively.
New Jersey is widely known for the high population of Indians living in the city. I have read in newspapers and on the internet about various cultural festivals and traditions being celebrated at New Jersey. My curiosity "How must Indian festivals be celebrated in a foreign country?" has arose ever since.
My suggestion;
I have read about New Jersey's vibrant culture, especially with a large proportion of people with Indian origin. I was surprised when I found out from newspapers and internet about how grandly some Indian festivals are celebrated in such a far away foreign land. This fact not only developed a strong liking towards New Jersey, but also a strong desire of experiencing such diversity.Also, I suggest you to include this part into your first para. This idea goes well with the previous lines too :)
