Registro: padres ciudadanos registrados/exciudadanos de la India independiente

Clause (e) requires (1) full age and capacity (§2(1)(e), §2(4)); and (2) that BOTH the applicant's parents are registered as citizens of India under §5(1)(a) or naturalised under §6(1). It imposes no residence-duration requirement. Clause (f) requires (1) full age and capacity; (2) that the applicant, or either of his parents, was earlier a citizen of independent India; and (3) twelve months' ordinary residence in India immediately before the application. Both clauses are subject to the §5(1) chapeau (not an illegal migrant; not already a citizen), the §5(2) oath for a full-age applicant, and the §5(3) prior-loss bar. The §5(3) bar is particularly relevant to clause (f): where the clause (f) applicant is himself a former Indian citizen who renounced, was deprived, or whose citizenship terminated, registration is available only by order of the Central Government. The grant under both clauses is discretionary under §14, without assigned reasons, and final subject to §15 revision.

An adult applies to the Central Government in the prescribed manner for registration under §5(1)(e) or §5(1)(f). For clause (e), the Central Government verifies that both parents are registered under §5(1)(a) or naturalised under §6(1); for clause (f), it verifies that the applicant or a parent was earlier a citizen of independent India and that the applicant has twelve months' ordinary residence (relaxable by up to thirty days under §5(1A)). If satisfied, it may register the applicant; the grant is discretionary under §14 and final subject to §15 revision. A full-age applicant must take the Second Schedule oath before registration (§5(2)); on registration the person is a citizen by registration from the date of registration (§5(5)). For a clause (f) applicant who is himself a former Indian citizen, the §5(3) prior-loss bar requires a Central Government order. The no-dual spine (Constitution Art 9; §9) applies on acquisition. Government fees and timelines are operational figures not asserted here.

Route IN-REG-05 covers two adult registration categories in §5(1). Clause (e) empowers the Central Government to register a person of full age and capacity whose parents are registered as citizens of India under clause (a) of §5(1) or under sub-section (1) of section 6 (i.e., whose parents themselves became citizens by §5(1)(a) registration or by §6(1) naturalisation). Clause (f) empowers registration of a person of full age and capacity who, or either of whose parents, was earlier a citizen of independent India, and who is ordinarily resident in India for twelve months immediately before making the application. Both clauses are part of the §5(1) text substituted by Act 6 of 2004 (w.e.f. 3 December 2004). The clause (f) residence phrasing 'is ordinarily resident in India for twelve months' was itself substituted by the Citizenship (Amendment) Act, 2015 (Act 1 of 2015, w.e.f. 6 January 2015) for the earlier 'has been residing in India for one year'. The §5(1) chapeau conditions apply to both: the applicant must not be an illegal migrant (§2(1)(b)) and must not already be a citizen.
