I completed my interview June 10, 2019 for my Nexus and was approved. They said it will take between 3 - 4 weeks to receive my new card in the mail.
I forgot to ask if I can continue to use my old card while I wait for new card. I was able to do this the last time I renewed as I was crossing the border the same day.
Everything is the same except I am now using my maiden name.
