This ‘visa application’, and in some cases, ‘legitimization of free mingling of the girl and boy’ has led to many nikahs being done prematurely…and the worst part is, noone takes it seriously. i-e, if the girl and boy end up staying together overnight after the ceremonial nikah, its considered a stigma, if not a sin.
Its sort of like how people will lie, cheat, steal during ramadan, but if they see someone eating in public, they will beat them to a pulp for desecrating the holy month.
