I think I may have discovered the one of the most important (unwritten) rules the Immigration Offices use to evaluate permanent visa applications.

My permanent residence visa was issued without much hassle in July 1995 17 months after I applied I believe because I clearly illustrated to the immigration officials that my plan was to reside "permanently" in Japan and that I'm trustworthy--my Japanese wife and I invested in the country by purchasing a condominium (mansion) (ie.can't run away easily) and I was a regular staff member of a 250+ Japanese electronics corporation.(stable income)

Also I believe the name "Permanent Visa" is totally misleading--it should be though as a "Trustworthiness Certificate"--the unexpired visa status is just a bonus.

As soon as I received my Permanent Visa, I immediately noticed an increase in the respect I received from Japanese officials. Bank managers and lawyers started listening to me when before they would not. Narita airport Customs officials don't hassle me as much now, and my Japanese business associates start introducing me to new business opportunities. That's the real meaning of the Permanent Visa--and why I believe Immigration officials are correct in demanding that applicants prove to them that they are "trustworthy".

When you've passed through all the trustworthy tests: the 1-year, 3-year visa hurtles, paid your taxes, have a steady job and your neighbours/Japanese coworkers/friends will provide a good report to the police that come to inquire about you, I'd ask yourself one more important question before submitting your application for a permanent visa--if I was a Japanese official, would YOU certify that this person is trustworthy? If your application is able to show that other Japanese trust you, I believe you'll have a permanent visa soon. If not, I'd recommend to put some effort on improving the image of your trustworthiness.

You are also probably wondering how we managed to convince a bank to loan us money to invest in a condomium (mansion) in the first place without a permanent visa. Again, illustrating your trustworthiness (plus a 25%+ downpayment) is the key as is making friends with a bank employee. Remember, in Japan relationships and connections count more that we imagine.

I hope my comments and experiences will help you obtain your permanent residence visa soon as well.
