DL profiles versus second passport
I am running out of pages, not time, on my passport. Since we can no longer simply add pages I need to get a second passport as I do not want to lose visas like the one for China in my primary passport.
I know the DL profile only allows one passport so what will I encounter when on a particular trip I want to use the second passport? I also wonder if I will encounter DL issues even after registering the second passport with Global Entry.
