As you probably figured out, there's no such thing as an Osaka Foreign Relations Bureau.  I thought this was a humorous idea for a dream but it would probably be funnier if they actually existed.  Don't you think it would be funny if foreigners were being regulated in this way to keep the expat population low?  How many people from each race would be allowed into each city?  If something like this happens for real in Japan, I'm going to be so mad!  Of course, living there can make you feel like telling any other foreigners you see, "Hey, great job!  You got in!"
