Are you independent? Yes, the application is pretty straightforward. If you are working 20 hours per week, you may not qualify if you are a family of 1.
Based on what you wrote you will not be eligible for food stamps. Double check the policies in your state.
You must be part of a federal or state funded work program where you work 20 hours a week
Are you on public assistance or disabled
Do you have a child who is under five and you are the primary care taker
I know of students with disabilities that preclude part-time employment, who receive food stamps. The ones I know are on government assistance in other areas as well (such as Medicaid). Once a student is over 21 the parent’s income is not considered.
Agree with @scmom12, many of the SoCal CC’s and state colleges have Food Pantries. You can go to the Student Unions to get more info on hours and products.
