I got my American tourist visa to transit through Newark Airport, flying from Toronto to Frankfurt. Since this was my first time in America and at an US airport, I wasnt sure of the regular steps to transfer terminals and go through immigration and checking. As soon as I left the bridge, people who wanted to move to other terminals were heading to a stairwell nearby which brings them to the Airport terminal transit buses. I followed them and reached the designated terminal for my next flight.
After reaching my final destination and got my passport stamped I realized I missed out my American security/immigration exit stamp, which would denote I was in US only for couple of hours.
Its been four months since this happened and I am worried that I just spent four months out of six off of my US tourist visa. Would I be able to explain to US immigration/security officers about this on my next visit and have six months intact on my visa?
