Do I require I-797A and I-129 from my previous employer for H1B stamping?

Hi,

My previous employer sponsored H1B visa for me and received approval from USCIS. But even before October 1, I joined new company. This new company had already transferred my H1B and also received approval. Now I am going to schedule H1B visa interview sometime in Jan'14. I just wanted to know if I need to carry I797A and I129 from my previous employer with me for interview? I do not have those documents and I dont think my previous employer will provide me those documents. All I have is scanned copy of I797A sent  by my previous employer.

BTW my current employer has provided me with all the required documents. Please advise. Thanks!

its better to carry I797 and I129 from previous employer… Best of luck…
