We were told by immigration that affidavits are compulsory, even though the kids have both passports ...
From the 2023's Regulation , Article 1 and 8 (see below) I understand that the Affidavit may only be required if a dual citizen has only a foreigner passport and needs to enter Indonesia without an Indonesian Visa (or Re-Entry Permit) , and live in Indonesia without an Indonesian Stay Permit . Even in this case I understand that the Certificate of Registration of dual citizenship (Article 7) could be used , instead of the Affidavit . At the end , I cannot understand the existence of this Affidavit .
