I am applying for US F1 visa. My old passport had some mistake in my surname. So I got a new passport two years back. I did not know that I may need my old passport during the visa interview. My sister took my old passport saying that she will play with it. When I asked the passport back I discovered she has torn down two of its pages, including the first page where they put the CANCELLED stamp. All the personal information pages are intact. Do visa officers scrutinize the old passports ? Now what should I tell the visa officer if they ask me about the missing pages ?
P.S.: My old passport did not have any visa stamp on it.
