What ICA actually requires
Start with the visa-class requirements, not a generic checklist
The PNG eVisa system asks applicants to choose a visa type first. The portal then tells the applicant which supporting documents are required for that class before the application can be lodged. This is important because a visitor application, business application and specialist visa do not use the same evidence.
ICA's eVisa workflow places document upload before final submission and payment. Once the required details and attachments are complete, the applicant proceeds to the fee stage; after payment, the application is submitted and a receipt email is issued.
