The passport process for infants involves standard verification steps, including a potential visit to your local police station. While some Tatkal applications may proceed without a physical verification call, you should be prepared for the police to contact you; if they do, bring your baby, your address proof (matching the lead applicant's address), and any necessary identification. If you haven't received a call and your travel is imminent, it is proactive to contact your local station to confirm the status, as they can often facilitate a quick verification visit.
