Visitor Visa - B2

This is the experience that I had in the month of November at Delhi Embassy. I am 27 years old with a permanent government job with 2 years of work ex in private sector, 2 in Public sector bank and finally made a switch to government job. I was dressed in formals with probably favourite combination of americans i.e. Grey business jacket, Light Blue shirt and navy blue trousers. This is how the experience went

Now all this while she was typing simultaneously I was pretty confident that i’ll get through with the it until she dropped the bomb uttering these words “I am sorry, You are not issued visa this time but you may try again” and handed over section 214/b refusal. Now, for all those who say it is the sheer confidence, honesty etc etc that gets you through I doubt that. I had all the possible docs you name it I had it to back up my case ITR,Bank Statements, Service/employment letter from government with clear joining and retirement age, affidavit of support but still I was refused. Now the question arises how can one prove his ties when he has a govt job with all the benefits, own house and old parents to take care of. There were people who were fumbling, thinking taking pauses before answering and unconfident but still they got through. Now I did everything right under the sky all my answers were in line with DS 160 but the outcome was negative. I was confident, straight forward, rock steady, fluent clear and precise while giving answers but still it didn’t go my way. It is altogether a different ball game inside. God, alone knows what permutation & combination they are looking for or are they simply making money by exploiting people of developing nations by asking them to spend time and again on their visa application. For those of you who say it is better to visit south east countries before applying to US, why should onespend unnecessarily on a place you don’t even a wish to go and why not apply to the place which is beautiful and where you have relatives to get along? Though I was going there to spend my hard earned money anyway it is their loss. Still I would like to know what went really long in my case cause to this day I am completely clueless. Any help or suggestion is appreciated.
