Yesterday, on 6th May, I took a day off and went to submit my passport
issue. The passport office around my place was on the groud floor of
Technomart, Gangbyun.

I've just waited for half an hour, and easily succeeded to submit. I
took a instant photo, and the officer said initially instant photos
are not allowed but she'll accept mine under my confirmation. So keep
in mind that if you have plan to issue a passport.

It'll take 3days until the issue. I made a electronic passport, so
that I can travel to US without visa up to 90 days.

It's a good start! :)
