To And From Nepal Anytime
This border movement arrangement between India and Nepal is a fine example of freedom of movement. You can go to or cross over from Nepal anytime without the usual bureaucracy and red tape that you can expect to get at home, for instance when going to or coming from Canada or Mexico.
Of course, some people would poke holes in this arrangement but it remains a win-win for the governments and citizens of both countries. There are numerous benefits, for instance, it builds and solidifies the relationships between Indians and Nepalese people in addition to facilitating cross-border trade and even international cooperation between India and Nepal.
