Studying From Outside Us On L2 Visa

Hi Friends, I am holding L2 visa. We were supposed to move to NJ by this month end but unfortunately our moving to US has been delayed by few months.

I am a teacher and wish to work as a teacher once I am there. I want to know what all are the requirements to be a teacher in US and can I attain the required qualification through distance learning to be a teacher in US, being on L2.

During this movement time lag, I want to equip myself with all possible things required to be a teacher there. Please suggest me if this is possible.

Thanks in advance for your valuable feedbacks.
