Each IEO project on XPAD is unique and therefore has different KYC requirements. These may include the exclusion of citizenships from certain countries, known as “restricted areas”.
Check where the restricted areas are in the information summary column on the right side of an IEO’s page on XPAD.
As such, you may not be able to join an IEO if your nationality is not listed as eligible in certain geographical areas. If so, you may need to select a different IEO.
