I have a folder with all of my documentation (excluding lung x-rays- too big to fit in the folder). In the folder are invitation letters; release letters; references from employers in both China and the UK; academic records and transcripts; birth certificate; teaching certificate; tax records and even an original of a certificate when I went back to college to do a course in sound engineering (hardly relevant).

I keep all my documents with me in china,except for word processing certificate I got when I was on the dole and which I now lost. Birth cert not really needed in China, but I do have it. Lung xrays seem a bit overkill, especially as it is all digital machines now?

Good luck
