Solution:The Central Government made a provision for registering as an overseas citizen of India card holder under Section 7(A) of the Indian Citizenship Amendment Act, 2015. Eligibility to register as an overseas citizen of India card holder is-
(a) Any person of full age and capacity,
(i) Who is a citizen of another country, but was a citizen of India at the time of, or at any time after the commencement of the Constitution, or
(ii) Who is a citizen of another country, but was eligible to become a citizen of India at the time of the commencement of the Constitution; or
(iii) Who is a citizen of another country, but belonged to a territory that became part of India after the 15th day of August, 1947; or
(iv) Who is a child or a grandchild or a great-grandchild of such a citizen; or
(b) A person, who is a minor child of a person mentioned in clause (a); or.
(c) A person, who is a minor child, and whose parents are citizens of India or one of the parents is a citizen of India:
(d) Spouse of foreign origin of a citizen of India or spouse of foreign origin of an overseas citizen of India cardholder registered under Section 7-A and whose marriage has been registered and subsisted for a continuous period of not less than two years immediately preceding the presentation of the application under this section: Provided that for the eligibility for registration as an overseas citizen of India card holder, such spouse shall be subjected to prior security clearance by a competent authority in India:
Provided further that no person, who or either of whose parents or grandparents or great-grandparents is or had been a citizen of Pakistan, Bangladesh or such other country as the Central Government may, by notification in the Official Gazette, specify, shall be eligible for registration as an overseas citizen of India card holder under this sub-section. Thus Indian, who migrated to Pakistan after the partition, is not eligible to register as an overseas citizen.
