URGENT: Lost documents - H1B visa renewal - Dropbox

[sainadhnyc]

Hi,

 

I am travelling to India and I would need to get the H1B stamping done as my prior visa expired. Also while booking the appointment it said I am eligible for dropbox. 

 

However today I realized that I dont have any of my original documents (i-797, i-129, etc). Also there is no way that i can postpone my travel plan. 

 

Would a carrying a copy of i-797 suffice for the purpose of visa renewal? 

 

To get a duplicate copy of i-797 from USCIS, my employer needs to apply form i-824 and generally it takes 3-6 months for USCIS to issue a duplicate copy. Is there any premium processing to get duplicate i-797?

 

Thanks
