i am very much thankful to the members of this forum for their help. My work place was closed on 1/7/2010 and i provided the letter of employment and my tax documents for the period i worked there. now i have sent the visa officer a new letter from the employer, my tax returns, group certificates, personal letter from me, letters from my previous work mates and their tax returns, new business card of my previous employer.
All inputs from the members are more than welcome. thankyou all.
