I feel like many of yall are ignoring or have not realized that it is not a "work permit" per se. We will be allowed to work, but we will not accrue legal presence. So anything that a normal work permit allows such as leaving the country will not be the same with the EAD. Also the deferred action does not grant you complete immunity from being deported. It will only protect you from being detained for not being able to prove legal presence. For example if you are arrested for DUI and they find out you're undocumented after you have deferred action you can still be deported.

This is all how I interpreted what I read on the ICE and USCIS websites. Feel free to correct me if I'm wrong.
