OK so I'm one of those people that did not do enough research before applying for GE - just got GE and now realize I should have probably got Nexus as I typically travel to Canada 2 - 3 times a year.
If I were to apply for Nexus sometime in the near future and the GE "converts" to Nexus would the expiry date of Nexus be 5 years from approval of Nexus or 5 years from approval of the earlier GE application?
