FlyerTalk Forums - Applying for NEXUS after having Global Entry (i.e., Replacing GE with NEXUS)

How do I add NEXUS to my existing Global Entry membership?

On the TTP home page, select "Manage My Membership"
Log in
Then click on the "Add Trusted Traveler Program." Make any changes necessary
On the U.S. Customs and Border Protection (CBP) Trusted Traveler Program List page, select the checkbox next to the NEXUS option
On the next page you will see the NEXUS logo. You will need to provide additional information and answer questions; (some of these questions are very similar)
Once all the application information is entered/ corrected, certify your application and pay the fee
Applicants seeking to use NEXUS to enter Canada must complete an enrollment interview with the Canada Border Services Agency (some with GE received NEXUS card without interview)
An iris scan is needed; contact lenses must be removed to do the initial scan. Scan does not have to be done at the same time as the interview
