i got approval letter one week after i had my interview
officer wanted to confirm and review all my travel record, i had a lot of short trips,
officer wanted to confirm all the stamps regarding departures and arrivals,
during the interview i had only my recent travel document, it did not have all the
stamps, i told the officer i mailed all the old travel documents to nebraska center each time i applied for new travel document,
my officer told me thay she can not make a decision until she review my travel record,
i was approved one week later
