India has a ban on "repeaters" and excludes applications from anyone who has previously performed the pilgrimage through the national Hajj committee, although there are exceptions from those accompanying certain categories of people like the elderly.
With a restricted supply of Hajj spaces, it's inevitable that people will try to find ways to get to the holy city and stay there.
In April, to curb unauthorized Hajj pilgrimages and control inbound travel, Saudi Arabia suspended the issue of short-term visas for 14 countries: India, Pakistan, Bangladesh, Egypt, Indonesia, Iraq, Nigeria, Jordan, Algeria, Sudan, Ethiopia, Tunisia, Yemen, and Morocco.
People have in the past traveled to Saudi Arabia on short-term visas and entered Mecca without official permission for the Hajj. Authorities said that many of those who died in the heat during last year's Hajj were unregistered and unable to access air-conditioned pilgrim amenities.
