Did you have the invitation letter notarized? It's been a while and if your husband has already sent his application then he doesn't need it anymore. It's just one letter (invitation and statement of undertaking), except that it gets notarized.
Ok thnks jobseeker! Remembee you help me with my letter for my husband? And now i will have to tell my friend/employer that she should get a notarized statement of undertaking?
