<p>I do not and have never have had contact with my father. On the common app what should I do leave them blank or put n/a? I have NEVER known anything about him except for his name. Also I'm a only child living with a single mom. For the siblings section and legal guardian section do I leave those blank? Finally My mom is not employed and receives SSD. How would I put that down on the employer and occupation line?</p>
