Need your guidance for the rejection of my F2 VISA

Hello Team,

My wife has US Student visa.She is studying at Arkansas state university from March 2016.I applied for the F2 visa multiple times but got the rejection every time.Is there any procedure that we can know the reason of my rejection?

May be because they think you have a job here and looking to immigrate to work in USA. Or she is in the final semesters of her education or going to finish up soon.
