If I work on OPT as a volunteer, will my OPT extension be rejected?

[DesiOPT-FaceBook-Admin]

I have completed Master in Computer Science and graduated in January 2013. Since Jan, I didn't have a job and looking for it. My OPT starts on February 2nd 2013. In April, I have submitted the consultancy name to my school and told them I am working as a volunteer in the company.
-Do I need to submit any document anywhere apart from my school.
-Now for OPT extension, when do I need to apply.
-If I work on OPT(1st year) as a volunteer, will my OPT extension will be rejected.

You wont be rejected if you work as a volunteer

apply November 2014 for the extension. your consultancy should provide u with a letter saying u r working with them since january. the letter should contain everify number of the consultancy. without everify number you r screwed. but they will certainly help you out. dont worry, your situation is not bad and u r planning ahead. good job
