In case of adults, generally, 10-year validity Passport would be issued. In case of minors, the validity of Passport is restricted to 5 years or till they attain the age of 18, whichever is earlier. But the minors between 15 to 18 years of age can apply either for a 10-year validity Passport or for a Passport which is valid till they attain the age of 18 years. Different fees are applicable for different validity. Further, most of the foreign missions/embassies insist on the Passport validity of at least of six months to one year before they consider issuing visas. Accordingly, it is advisable to apply for re-issue well before time to avoid last minute rush.
