Hello Nandani,

The best cities to pursue company secretary jobs will be cities with developed industries or cities that have a good standard of living because these cities will have more corporates and conglomerates. You can see a list of job vacancies for company secretary here : https://www.google.com/amp/s/www.monsterindia.com/amp/b-com-company-secretary-jobs.html

As you can see, most of the jobs are in Mumbai, Chennai,  Bangalore and Pune. You can proceed accordingly.

Hope this helps :)
