I'm unemployed with $30,000 credit card debt. It's piling up and I can't pay nor can I afford a bankruptcy attorney. If I find work can they garnish my wages?

If your creditors obtain judgements in court, then yes, and portion of your wages may be garnished. 

I know money is a problem but if you were considering bankruptcy you can file yourself.  I'm going to give you a link to a site that will explain the bankruptcy basics.  You will want to look at the information for a Chapter 7 filing; it will also supply all of the forms that you will need:  http://www.uscourts.gov/bankruptcycourts.html

Also, you can see if you qualify for representation by Legal Aid.  Additionally, if there is a law school nearby see if they have a legal clinic; they typically handle these type cases.  Finally, you can contact you local county bar association and see if they have a list of attorneys that will handle your case "pro bono (for free) or at least take your case on a reduced fee basis considering the circumstances.
