When filling out the I-765, it says under,
Information About Your Last Arrival in the United States
There is a prompt for,
21.b. Passport Number of Your Most Recently Issued Passport
Obviously that should be the most recently issued passport, but what about
21.e. Expiration Date for Passport or Travel Document
should that be the most recently issued Passport, or the one you used on your last arrival in the USA?
