No they already started
As of June 19, 2023, we started to issue the new passports. Until we finish installing the printers for the new passports in all offices, you may still get the current passport when you apply. By spring 2024, we’ll only be issuing the new passports.
If you already have a valid passport, it’s still secure and reliable. You don’t need to apply for a new one.
