Switching Town List for Civil Service

You can change them as frequently as you want. Up until I got on as a reserve recently, I had changed my towns several times. You just either need to fill out that form on the civil service site or sending them a letter will work just as well.

You need to consider the size of the town you are placing yourself on as well. I am 7th on a list, as a non-resident for a town, but when you think real hard about it, it's not that hot. By the time this really small department hires 3 full-time guys (2+1 formula) I'll be about 90 years old, just because it's a smaller town which does very little hiring. So while putting your name on the list for a small town, to get high on the list might seem like a good idea, you have to look at the departments hiring practices as well.
