Paki Girl, dont worry, Insha ALLAH all will be fine. If you have provided enough proof of your relationship and presented them properly, this little mistake doesnt count. Spousal sponsorship have three main important factors: Eligibility of sponsor, Genuinty of Relationship and background checks for applicant. Your relationship is Genuine and made by ALLAH Almighty, so no one on this earth can doubt on that.The maximum they can do is to call for an interview to clear the doubts, which will delay the case, but they can not refuse becasue of the existance of other proof. So now on, start gathering more proof, save all the chat logs, telephone bills, receipts of money your husband is sending you etc etc.
