FINALLY ...

... my letter has arrived. Now I can get on with the process of obtaining my visa. The first big step on the road to Bangkok. It's actually more official that I had asked for and pretty much the same one they will use to apply for a work permit on my behalf.
You will have read earlier (if not, why not?) about the problems of being called an editor, even though that is exactly what I will be doing - well, my title for 'government' purposes will be 'foreign marketing manager'. Good eh?
