Visitor Visa - B2

I am 23 years female.I have never travelled to any other country before, this was the first time I was applying for visa.I read many blogs on net stating that its very difficult getting visitors visa for young unmarried females. But believe me its nothing like that, its just that you should be genuine and confident. Even I got scared after learning all these stuffs from different people and websites, but I trusted god and went with confident for the Visa interview at Mumbai Consulate.The VO asked me the purpose of visit,where I am working,how much is my annual earning and how am I going to finance my trip. After that she told me OK we will issue you the visa.My purpose to vist US was personal and not related to business, but next day when I received my visa I was glad to see that I got 10 years multiple entry B1/B2 visa.
