Produce Atested Marriage certificate to wife sponser and ask fr a release,here as Darude said it is HR screws up,if she has acess to sponser ask her to meet the sponser and explain,definitely they will oblige and no chance of messing up,do not inform HR or Mandoop if she is aproching sponser directly as 100% they will confuse and spoil entire Broth.
