Losing the status of Permanent Resident:

I am a PERMANENT RESIDENT, for how long is it valid and what do I need to do in order to avoid losing my status?

The permanent residency is valid for life if you live in Argentina, and for you not to lose it if you live abroad, you need to make sure that you visit Argentina at least once every 2 years. So now you have the perfect excuse for your holidays in Buenos Aires at least once every two year!
