i am a wife sponsored my husband
its a good idea but its not mandatory..its gud if you can do it but if you already provided them with all the wedding(like wedding plus reception) and post wedding photographs(dinner/outing bla bla) then that should be ok i think yours is a full wedding so there shouldnt be a problem...
just keep the proofs of communication and strong relationship like phone bills/cards/emails/skype/joint bank account etc etc and the most imp thing keep praying and keep your faith in Allah and you will be done soon InshaAllah!
good lukc
