Visitor Visa - B2

I had appeared for B2 Tourism Visa with my wife. The experience was not so good.

Location : Delhi

I had been reading immihelp since last month to get more and more and information. During this month I did collect all the major supporting documents. And made sure that I have enough balance in my account. I am 27 years old and got married just 10 months back. I was so excited as I had planned to go outside India with my wife to have some fruitful time. I am a business man and getting good money every month. I have my own IT business and have been running successfully for last 2 years.

It was nice weather on the day of interview. and I was fully confident with all the positive feelings.
Reached Embassy. Submitted phone there, went inside, there was checking point.
Waited for my batch turn. They took fingerprints once again and now it was turn to be interviewed.
It was a long queue, while I was standing in a queue I got chance to view the face of 7 chancellors, did not get chance to see others faces. There were almost 10-12 chancellors.

There were two Indian chancellors who were speaking in Hindi and sometime in Punjabi. All the others were foreigner. There was a Old lady with charming and smiling face, she was very pretty and happy b y nature. I noticed 2 people who were interviewed by her and believe me, chancellor and interviewee both were laughing loudly, it seemed to me as both of them were cracking jokes to each other. I was just praying I want to be interviewed by this lady. Now finally it was my turn, unfortunately that lady was interviewing someone else and I got some other chancellor, I didn't want to be interviewed by this chancellor as I didn't like him as he was looking like he is little bit angry.

Questions that he asked to me

ME : Good Morning
VO : Good Morning(replied, some chancellors never reply but he replied)

VO: May I have passport
Me : Yes, this is mine and this is my wife's.

VO : Why do you want to go to US?
ME : Just for Tourism.

VO : Where do you want to go?
ME : We want to New York, California, Washington dc, Niagara, I have not competed my plan yet, I am in touch with Thomas Cook, May be I add some more places.

VO : What do you do?
ME : I have my own business, we provide website, it and network support.

VO : Have you ever visited abroad?
ME : No.

VO : Do you know anyone is USA?
ME : No

VO: What do you do Mam (to my wife)?
My Wife: Pardon me!!

VO: He repeated what do you do?
My Wife : House maker.

VO : Do you have kids?
ME : I said No

He did type something on his computer for few seconds and then he said with his smiling face " sorry we cannot give you visa this time"

He returned my passport and gave me slip. I asked him why you can't he said read it.

I don't know what went wrong as that letter states that I don't have strong ties with my country. I have a good business and good earning, I earn more than 2 lakh in a month and did mention 2 lakh in DS 160,

Any expert there who can just tell me what wrong happened with my case?

I want to apply again and please suggest me when should I apply again?
