I married my wife in Jan 2010 abroad (im a British citizen) and stayed with her for 6 months, upon coming back to the Uk i was left without a job for some time. I wanted my wife to come and visit me so i asked my sister if she can sponsor her on my behalf and she agreed. We made the application and provided all the paper work regarding my sisters income, work, bank statements and tenancy agreement.
The ECO refused her entry due to the lack of information from my behalf.
Below is a copy of the notice.

I wish to appeal it as i can provide documents now as i am working.
Would my payslip and bank statement be sufficient?
any help will be great.
Thank you.
Ps. Only reason i didnt apply for spouse visa at the time was because i was unemployed. I do intend to apply for a spouse visa at a later time as she is still learning English.
