The CGI Birmingham site mentions that there is 3 months grace period when no penalty will be applied if someone travels on Indian Passport after acquiring foreign passport.
Can someone please confirm if HCI London follows the same. HCI London doesn't mention that and also can't find this on VFS site, since now they are handling the "Indian Passport Surrender"
