Quick Summary

Indian citizenship acquisition and termination is governed by constitutional Articles 5-11 and the Citizenship Act, 1955. Five modes of acquisition exist: birth (jus soli with parental conditions), descent (jus sanguinis for children born abroad to Indian parents), registration (for specific categories like spouses and persons of Indian origin), naturalization (for foreign nationals after 12 years residence), and incorporation (automatic for new territories).

Three termination mechanisms operate: renunciation (voluntary surrender), termination (automatic loss upon foreign citizenship acquisition), and deprivation (government action for disloyalty or fraud).

The 2019 Citizenship Amendment Act introduced religion-based fast-track naturalization for specific minorities from Pakistan, Afghanistan, and Bangladesh, reducing residency requirements from 12 to 6 years.

Key constitutional principles include single citizenship (no dual citizenship allowed), parliamentary supremacy in citizenship matters under Article 11, and protection against arbitrary deprivation. Historical context includes partition-era provisions in Articles 6-7 addressing refugee situations.

Contemporary issues involve National Register of Citizens implementation, CAA constitutional challenges, and statelessness concerns. Supreme Court judgments like Sarbananda Sonowal have shaped immigration policy and citizenship verification procedures.

Documentation requirements vary by acquisition mode but generally include birth certificates, passports, and proof of residence. The framework balances inclusive citizenship policies with security concerns and demographic considerations.
