I wish I could help you, but this stuff is not at all clear to me.
This site might help. https://www.cpamobility.org/
When I put in Illinois and WI for performing the work, I get “Individual mobility is available (with no further filing or fee) if you hold an active unrestricted CPA license in your principal place of business. “CPA license” means a CPA license granted by the state board after all education, exam and experience requirements have been met.”
So it looks to me that you're currently applying for a license in Illinois, right? There's an option on the NASBA websites for transferring your scores to another state. But if you want to stick with applying under the Illinois Accountancy Board umbrella, then it seems to me that as soon as you meet the experience requirement to become a fully licensed unrestricted CPA in Illinois, you can practice in Wisconsin with no problems whatsoever.
I have a somewhat similar issue…..
In my case I am obtaining a non-reporting CPA license in the state of Massachusetts. I am doing this because in MA you can get a non reporting CPA license and call yourself a CPA WITH ZERO WORK EXPERIENCE if you 1) have a graduate degree in accounting/finance/etc & 2) have obtained 150 credits.
A non reporting means you have all the benefits of being a CPA (call yourself CPA on resume etc) but you cannot sign off financial reports until you get 1000 hours of attest experience to upgrade to a full reporting license.
The issue is I will be applying for jobs out of Massachusetts and would like to obtain a CPA license in a different state through reciprocity. So it looks like if I get a non reporting license in MA first, I will still need to obtain 1000hours of attest experience to eventually upgrade it to a full reporting CPA license in Massachusetts. I'm guessing that other states will look at a non reporting MA CPA license as restricted and that I must therefore first fulfill this 1000 hours experience requirement in MA to apply for CPA reciprocity, correct?
