3 months is not entirely abnormal for a summer NEXUS Card application. CBSA and CBP will not call you to notify you of your NEXUS application status. How you check your status depends upon how you applied:
- If you applied using TTO, login to your TTP account to see your status.
- If you applied by mail to the CBSA office in Niagara Falls, you have to wait until you receive the conditional approval or refusal letter. If you have reason to believe that the letter was sent and you never received it, you can try calling them at 905-354-0656.
- If you applied through a private company, contact them for your status.
