I have my green card and am awaiting Form 4s, but I was wondering - what happens if the politics in my town change and the COP decides that they won't renew my green card? What options do I have? Would it still be possible to sell the item to someone else? (With the wait times on form 4s, I tend to doubt it) or would my only option be surrendering a registered MG to the ATF? (Tragic and expensive?)
