No employment agent may open, conduct, or maintain an employment agency at any other place than that specified in the license without first obtaining the consent of the commissioner.

Such consent may be withheld for any reason for which an original application might have been rejected, if such place had been mentioned therein. If such consent is given, it must be endorsed upon the license and, if such license is renewed, such other place must be substituted for the place originally named in the license. So long as any employment agent continues to act as such under the person‘s license, the employment agent shall maintain and keep open an office or place of business at the place specified in the license.
