Global Entry - Mexico to U.S. via walking [Do I need my passport?]
I have Googled and cannot get a recent answer for this. I live in San Diego. I have the Global Entry ID in addition to my passport. If I walk from Tijuana to get back to San Diego (via San Ysidro), I know there is the SENTRY lane where I could use my GE ID however, do I still need to take my passport with me?
