What is the quickest, easiest and cheapest avenue to immigration united states?  I have just turned eight teen years old and would love to get out of Japan.  I long for the freedoms of the U. S.  Everything here is so close, so monitored, there is barely enough room to breathe.  My family knows of my desires and would help me to get there.  Then I could find ways to bring them over with me.  I think there is much more opportunity in the U.S. for my family than there is here in Japan.  My family has been in the mercantile business for many generations.
