For mem­ber­ship in the IBU, a writ­ten appli­ca­tion (Full/Asso­ci­at­ed) to the branch office must be sub­mit­ted, with a com­plet­ed appli­ca­tion form. The Board of Direc­tors makes the deci­sion on admis­sions. The rules for mem­ber­ship are reg­u­lat­ed in the Bylaws and Mem­ber­ship Fee Regulations.
