A couple's first PR application was refused (an employment letter wasn't detailed enough). After re-entering the pool, getting a new ITA, and paying fees again, they asked whether biometrics done for the first application were still valid, especially since they'd proactively resubmitted the same biometrics for the new application without being asked.
What the thread clarified:- Biometrics are generally tied to your identity, not to a specific application. Once biometrics are on file, they get attached to your record whether or not you're asked for them again on a new application — so in most cases you do not need to redo them if your existing set is still within the valid window.
- A policy change effective applications submitted after June 14 requires new biometrics even if the existing ones aren't yet 10 years old. This is an important exception — if your new application falls after that policy date, don't assume your prior biometrics carry over; check the current IRCC instruction letter for your file, since rules like this can change over time.
- Practical approach: rely on IRCC's application-specific instructions (the letter requesting documents will say explicitly if new biometrics are required) rather than assuming based on past experience.
Because biometric-validity rules have changed over time, always confirm against your current instruction letter rather than what happened on a prior application.
