37岁签F1 被拒了，请高人帮我分析，怎么才能签过

刚刚被拒签

工作人员说只递交护照，其他资料要才递交。以下是签证具体过程：

VO:Hi
I:Good moring sir,this is my passport.I want to go to America study computer science.
VO:Do you have I-20?
I:Yes,(找I-20表格)
VO:How old are you?
I:Thirty-seven,This is my I-20 Form.
VO:Why do you decide to study?
I:Because I feel my bachelor degree and old knowledge can't support my career in the future.The computer science is increacing so fast, and in beijing, almost everyone has bachelor degree,I want to more salary and better position, in china, if a person has oversea education background then the person will has more oppotunity promotion, so I want to study in America.
VO:what is your over job?
I:My job now?
VO:yes
I:I am a project manager.(找工作证明)
VO:(示意不需要),sorry, I can't give you visa.(出示214表格，指示给我)the paper has reason.

我就这样被无情的拒签了
