NEXUS for new applications has a wait period of about 18 months currently in the NE district.
From the website:
Processing times vary by applicant, but on average you can expect your application to be processed as follows:
Global Entry: 4-6 months
NEXUS: 12-14 months
SENTRI: 10-12 months
FAST: 1-2 weeks
Some good news is that as long as you apply for your Global Entry renewal on time, you have a 24-month Grace Period, after expiration, so you don’t have to worry about being stuck.
