Each country, I will nationalize under one of my previous names. Then, I will get nationalized and citizenship (after reaching the qualifications). Immediately following I have a local attorney do a deed poll changing my name (to an entirely new name) prior to obtaining that countries passport. This way I am legally in possession of the various passports with seperate and totally different names.

Makes travel interesting (when immigrations / migration officials see the various passports with various names they get suspect, and I have to show them translated copies of the deed polls, but in general when I travel I only present the documents I am using the travel so that unless they search -I'm white so they almost never search me, just scare me for a tip- they only see the current travel documents.

I also get local drivers license for the country, local social security cards, and local other documents that help me and are valid in other countries.

Some people collect coins, I collect citizenship.
