Visas
Travelers to India can apply for a tourist visa from their nearest Indian Consulate or High Commission. This is valid for multiple entries for a minimum of 6 months from the date of issue. Given the nature of India's bureaucracy, the rules and fees for application change regularly, so it's best to check with your travel agent or with the relevant authority for the latest visa information. Accurately completed visa application forms must be accompanied by two passport-size photographs (on a light background) and the appropriate processing fee; apply well in advance to avoid unforeseeable delays. You won't be admitted to India unless your passport is valid for at least 6 months after your entry, and it should typically also be valid for at least 3 months beyond the period of your intended stay. Check for fee structure and more details at www.indianembassy.org. In the U.S., the Indian Embassy is at 2107 Massachusetts Ave., Washington, DC 20008 (tel. 202/939-7000); and there are consulates in Houston, New York, San Francisco, and Chicago. In the U.K., India House is in Aldwych, London WC2B 4NA (tel. 020/7632-3149; www.hcilondon.net). If you're applying for a visa in a country where India does not have a representative, you are advised to make inquiries at the nearest British authority.
A special permit is required for foreigners wishing to visit the Lakshadweep Islands, as well as remote areas such as Sikkim and Ladakh. For Lakshadweep, your permit will be arranged when your accommodations are reserved. Permits for the other restricted regions can be obtained in India; specific details are given in the appropriate chapters. Carry a number of passport-size photographs and copies of the personal particulars and Indian visa pages of your passport to apply for these permits.
