ballpoint

Stop going off at a tangent. Pointless jokes are integral to this thread.

As others have already said, you should ask at your local immigration office. Many of them have an information desk that checks your documents when you apply for an extension, so that would be a good place to start. One potential drawback to not having a passbook that I can see is that, in my local office, they need to see the balance updated on the day of the extension application. My bank (KBank) only give a statement showing up to the previous day's balance. I also need to get them to copy the last used page of my bank book (after making a transaction to get an entry for that day) while I'm getting the letter and statement. I know some offices allow you to get your bank letter and statement a day or more before making the application, which is why knowledge of local office requirements is vital.

Watch their little eyes light up.
