US denies visas to Hindu priests

Hindu temples and religious groups in the US are reeling from visa denials resulting in shortage of temple priests and stalled temple construction projects. Hindu priests, temple artisans and traditional temple architects are increasingly being denied R-1 religious worker visa because of US regulations weighed in favour of Judeo-Christian terminology.

If such is the case in US then how Christian missionaries are allowed a free run in India? They are forcing Hindus to convert to Christianity, whereas these Hindu priests and artisans seek visa for performing pooja in temples and constructing temples.
