Read the general life across the border overview
When a current status is close to its end date and the next filing is not yet complete, the risk is not just missing a deadline for one person. Each family member's authorized period should be checked separately, because dependents and the principal applicant do not always expire on the same date or under the same rule.
Map every expiration date in the household separately
A TN holder's admission period, a TD dependent's linked period, and any work authorization tied to an L2 or E2 spouse can each carry a different end date depending on how and when they were issued. Build a simple table of who expires when, and confirm it against the actual documents rather than assumption, since a dependent's period is not automatically identical to the principal's.
Know which option actually applies before the date arrives
Extending an existing status, changing to a different status, and departing and re-entering under a new approval are three different procedures with different timing, evidence and risk. Confirm which one is realistically available well before the expiration, not after it, since some options close off entirely once a status has already lapsed.
Build a contingency for a filing that runs late
If the next filing will not be ready before the current status ends, identify what happens if the deadline is missed before it happens, not while it is happening. That may mean adjusting the target filing date, arranging a trip outside the country timed to a new entry, or accepting that a period without authorized status must be avoided by pausing the underlying activity. Decide this in advance rather than reacting to it.
Put every household date on one page and keep it current
The mechanism that prevents a household surprise is unglamorous: a single page, kept in one place, showing every date that matters for every person, with the source of each date noted and a record of when it was last checked. The rows are the people. The columns are the end of each person's authorized period, passport expiry, any age threshold that applies, and any commitment already made that depends on those dates — a school year, a lease, an employment notice period. Building it takes an afternoon and it does several things at once. It reveals dates that do not align, which is common and is precisely the risk this guide exists to address. It makes visible the person whose position nobody has looked at, usually a family member whose part of the plan has not yet begun. It converts a vague sense that something expires in the spring into a specific day that can be worked backward from. And because it records when each entry was last confirmed, it exposes the entries that have quietly gone stale. Review it monthly rather than when something feels urgent, and have someone qualified check it rather than treating it as settled because it looks orderly. Hypothetical example: a household's page shows four different end dates where everyone had assumed one, and the earliest of them belongs to the person nobody had been tracking.
