Can EAD/AP be used for re-entry into US after an extended (over a year) stay abroad?

[eemig]

I am currently on H1B visa. I will be filing for EAD based on pending 485.

I am planning to leave for India for good soon. I am planning to apply for EAD and AP (hopefully get a 2 year term) as a backup in case I decide to come back anytime during those 2 years. Is there any

As per the AP (I-131) instructions - "You may apply if Form I-485 is pending, and you seek to travel abroad for emergent personal bonafide business reasons"

Any info, personal experiences will be very helpful.

Thanks!
