POE risk for green card holders

[didig]

I'd like to know if anyone has info. on the risk of losing the a green card based on the POE (for example Detroit vs. Miami or JFK...etc..) which one could be riskier or safer?

There is no such thing.

Why do you think you would lose your green card? If you have been staying out for too long, for example, you may lose at any POE.
