To apply for passport services, one must visit the Passport Seva Portal and register as a new user by creating an ID. Once logged in, the applicant can select the required service and apply either by downloading and filling an e-form offline or filling out the application form online. The applicant must then schedule an appointment at the nearest Passport Seva Kendra (PSK) by selecting from available dates and either paying online or at the PSK depending on the location. On the appointment date, the applicant visits the PSK with the application receipt and required documents.
