Good Morning Everyone,

Been patiently waiting for my son's NEXUS appointment for literally years, from multiple cancellations due to government shutdowns and the pandemic and just having a hard time getting an appointment during a visit near the border. We finally have an appointment coming up in a couple of weeks at Fort Erie Ontario, driving from NYC. My question is, must we go back to Buffalo for the American portion of the interview immediately after the Canadian interview, or can we wait a couple of days and spend the weekend in Canada?
