trend has changed... this is old timeline not applicable for biometrics applicants.
There is no old timeline or new timeline when it comes to SS.
SS goes way deeper than just comparing your biometrics with international databases. That's at simple "Criminality" stage, among other things.
SS implies digging through all your potential connections with any suspicious activity.
For example, if you've been working in a company known for money laundering or fraud, you'd most likely fall into SS and be looked into to make sure you were not involved, and no amount of crystal clear biometrics will make it go any faster.
Another example is suspicion of misrepresentation. Contacts happen between different relevant authorities, and that can take a lot of time.
Yes, biometrics can be helpful to differentiate you with someone with the same name during the investigation and could make the process go faster than 6-12 months depending on the reason for SS, but it could also go much slower, as biometrics don't necessarily come into play in this phase.
Security screening is exactly what it means...
"Timeline not applicable for biometrics applicant"?... Everyone is subject to biometrics now.
SS takes a long time to clear... biometrics or not.
