Refund of relocation costs from the Arbeitsamt

Hello,
I have heard that there is a possibility to get the moving costs refunded from Artbeitsamt if you move to another city because of a new employment.
Does anybody know if that's true?
Thanx

but most likely only if you are unemployed before you take on the new job...

Cheerio

If you reduce commuting time by an hour, or start a new job, you can offset the moving costs against tax.
