i would not worry too much Katie, just make sure all the signatures r there, all the questions r fillled in (or written not applicale), both checklists r there and required documents, his photos with name dob and date when they were taken, the medical paper, receipt payment,....clearly separate ur forms, the applicant forms and the additional proofs put all in a box or envelope and good luck!!!!
AlieW, u got ur visa, very happy for u!!

13 is a lucky number for some

will u go together from the beginning or u'll go before? also before ur partner got his visa did they ask proof from ur side of relocation (visa cancellation in ur current country, resigning from ur job if applicable and stuff like that)? thanks
