The process of living in the country other than the native one permanently is known as immigration. This process can’t be processed without having passport, visa and OCI/PIO cards. The passport enables the emigrant to aboard the flight. On the other hand, the visa is a permit to live abroad for certain duration. Be it for half, full or many years, the visa endorses a licence to work, learn or visit outside legally. Overseas Citizens of India (OCIs) and Persons of Indian Origin (PIOs) cards allow validity to the foreigners for traveling in India without countering legalities. All these immigration elements can be applied online and offline. The competent authority ‘Ministry of External Affairs’ vets and validates this process. Visiting to Indian government’s formal website can be an unmatched and quick help for its seekers. Enclose the authentic proofs of applicant(s), address proof, ration card, driving licence, PAN card, passbook, school certificate, birth certificate and investment details as well.
