FRRO eVisa extension allows foreign nationals in India to extend their stay beyond the original eVisa validity through the Foreigners Regional Registration Office (FRRO) online system. Eligible applicants must submit an extension request with valid reasons, supporting documents, passport details, and current visa information. The process is completed online via the FRRO portal, followed by verification by Indian authorities. Approval is granted based on eligibility and documentation. This service is useful for travelers requiring additional time for medical treatment, tourism, or other permitted purposes. Applicants should apply before their visa expires to avoid penalties or legal issues.
