Cal. Code Regs. tit. 10 § 310.156
The Department will not issue letters of nondisapproval of advertising filed under Section 31156 of the Code. However, if the person desiring to use the advertisement requests an order shortening the three business day waiting period before use of the advertisement becomes permissible under that Section, such order will be issued when an appropriate showing of the need therefor is made by the filer. If a registration has become effective, such effectiveness shall automatically constitute an order shortening the three business day waiting period, with respect to any offering prospectus on file at the time of the effectiveness of such registration, relating to the offer and sale of the franchises covered by such registration, so as to permit the use of such offering prospectus at any time thereafter.
