Original I-797B has been lost. Is it a problem for Visa Interview ?

Dear Saurabh/All,

 My H1B visa documents are couriered from USA to India last month via. USPS and still not yet reached me.



When we enquired about this to USPS they said unfortunately they are unable to track my shipment and they are sending me claim form & insurance money. 



Now the employer is resending me all the documents and as u know the original I-797B was lost in the previous courier.



Will i be able to appear for the visa interview with the photocopy of I797B ? Will this a problem while my visa interview and how to handle the Vo officer?



Please guide



Thanks



Imran
