There has been a massive decline in the number of foreign tourists in goa, and according to a newspaper report, one of the reasons is that the indian embassies are making it difficult for tourists to get a visa
Specifically according to Herald newspaper report, Indian embassies are not giving visa to female tourists below the age of 25
Hence one of the major russian charter operators has stopped flights to goa after january 12, 2019
It is possible that the indian officials automatically link young female tourists to the sex trade, or may be harassed in goa by indian male tourists , so they are not getting visas
