Foreign nationals are not eligible to apply for an Aadhaar card. However, those living in India on a long-term basis, such as those with a valid work permit or residential visa, may be eligible to apply for an Aadhaar card. The issuance of an Aadhaar card to a foreign national is subject to the discretion of the issuing authority and may be granted on a case-by-case basis. It is recommended to check with the relevant authorities to determine your eligibility to apply for an Aadhaar card.
