To determine your OBC NL status your parents income is considered and not your income
You are not eligible for OBC NL if your parents income from business is more than Rs 8 lakhs per annum
for government employees only their position in the office is the criterion for non-creamy layer status. Excluding all Class I employees and direct recruits of Class II cadre, all other govt. servants having income greater than 8 lakhs are still eligible for the OBC non creamy layer certificates
