Lost the First Page of OriginaI-129

Hello,

As bad luck would have it, the first page (1 of 2) of my original H1B-Visa is missing. I have the second page though. I have a stamping scheduled in 3 weeks. However a photocopy of the 1st page is in place. Please let me know the process of getting another copy. Or whil the photocopy of the first page be sufficient.

Thanks

Mahesh
