Because I used to do such things for work and because I keep the information listed on the Imperial Site as part of the "Start Your Own Chapter" section, I check to see what states we are registered in.
As of this posting, the states are:
Texas - http://ecpa.cpa.state.tx.us/coa/servlet/cpa.app.coa.CoaGetTp?Pg=tpid&Search_Nm=empire%20of%20&Button=search&Search_ID=18606674549
Illinois - Verifiable at http://www.ilsos.gov/corporatellc/CorporateLlcController
Oregon - http://egov.sos.state.or.us/br/pkg_web_name_srch_inq.show_detl?p_be_rsn=1339340&p_srce=BR_INQ&p_print=FALSE
Arizona - http://starpas.azcc.gov/scripts/cgiip.exe/WService=wsbroker1/names-detail.p?name-id=05229520&type=CORPORATION
*Update* Nevada - https://esos.state.nv.us/SOSServices/AnonymousAccess/CorpSearch/CorpDetails.aspx?lx8nvq=f1QVSNIjjtHXXWFsawsV9Q%253d%253d
The States that need attention are:
Washington - No corporate listing
Utah - No corporate listing
If you see a state listed as needing attention and it is in good standing, please post here with the link so I know where to look for future reviews.
