Everybody should renew his cedula every 10 years. Doesn't matter if you are foreigner or a citizen. The difference is that a foreigner should add some extra police records documents when he wants to renew his expired cedula/ID every 10 years. Basically it's for life your PR from migration, except that Paraguay could take away your PR or cedula through the court only if you did some serious crime. Migration gives you a PR card, but Ministry of Interior through police instance gives you an ID based on your PR card. And that ID you need to renew every 10 years. Same for any other citizen of Paraguay.First you wrote the Residency has to be renewed every 10 years.
Yep, exactly : the document (ID) should be renewed.Do you mean the residency itself stays valid but the document has to be renewed every 10 years?
Through your stamp in the passport or searching in the data base of your legal migration movement. Nowadays if you leave Paraguay when you already have your PR and cedula (ID), they put a stamp in your passport and inside that stamp they write "CIP" which means "Cedula de Indentidad Paraguaya"/Paraguayan ID.How do they check, if I are absent for more than 3 years?
If you don't have citizenship your passport always should be with you. You can try to travel with ID/cedula, but migration board could always ask you about your passport because in your ID there will be always the nationality information. For renewing you should be in Paraguay, but with magic...maybe could be doneDo I have to renew it in Paraguay and do I really have to show my passport again? I want to have it as a backup, if my passport fails.
