I applied my xdsense account via VPN, I don't think it will ban you if you open in different country VPN, just think like a traveler living on his website and travel to different countries, and then ban his account?
It doesn't make sense.
I have to say, I have no idea if this will 100% OKAY, but I have read about, if you login two or more different adsense account in one PC, you are flagged.
Just do not open it in an abused Data Center VPN, also be sure to not open it in a different country earlier then 24 hours after opening in in another (say main IP location)
abused Data Center VPN
what does it mean?
