Handed over a yellow slip with nothing checked and a pink slip with everything checked.
My trip obviously will be cancelled as I have to reach US by 23rd for my training. and their process wil take at least 2-3 weeks.
Advice for all: read the technology alert list and if you by any way fall in that category, or are from a good college, do prepare a statement on how U r not a threat to U.S. else your trip will be delayed.
