I suspect you are referring to people of third world countries having to change their plans to or in first world countries, such as the U.S. and the U.K. due to rules being changed or at the whims of interpretation of rules by those charged with implementing them. It's an indication of changing economic situation. There is substantial economic activity in India, which of significant interest to western business entities. India, unlike the U.S. the U.K. or western Europe, does not face people trying to get in to India by any means, with the exception of Nepalis or Bangladeshis.
