Interesting about the 3 passport law. I had a situation where I needed to renew one of my two passports as it was almost out of pages, but it still had a valid visa that I needed. The lady (superviser, and really helpful), said it was out of the question to have 3 valid passports, and that she could let me retain the passport but she would cancel it electronically. This still allowed me to show the visa at the country in question, and they stamped me in on another of my passports.
