how does a brother officially visit a craft lodge under the grand lodge of india when he belongs to another constitution

An unknown visitor from another lodge or jurisdiction may enter a lodge only after passing a strict examination according to ancient usage, unless a brother present knows him to be a Freemason in good standing and vouches for his qualifications 1. Under general principles of Masonic law, the right of visitation is regarded as a landmark permitting affiliated Masons to visit regular lodges as divisions of a universal family 1. This right is not absolute; the Worshipful Master may refuse admission if he judges that admitting the visitor would impair the harmony of the lodge 1.

The specific administrative regulations and inter-jurisdictional protocol enforced by the Grand Lodge of India for foreign visitors are not detailed in the available sources.
