To gain permanent residency in a non EU country is not easy. Everything is temporary and you can keep your permanent residency at home.
And more cases, like one year contract sponsored working visa (which can be extended, but legally it’s still temporary)
I have temporary residency in the Philippines (one year ACR ID) and my permanent residency in my home country, Romania.
As my residency in the Philippines is not permanent (and I can’t get permanent unless I stay for 5 years) I can’t give up my residency from Romania (but I can move it to another EU state)
Please, we just had that discussion recently and I thought we came to a conclusion
It is not about permanent residency (in an immigration context) or not. The question purely is whether the OP still has a legal, registered residency in the EEA (basically does he still live within the EEA?). If so, he can keep the account, otherwise not.
