Answers: Depends, are you talking in the order of the Immigration and Naturalization Service(I.N.S.)? Or are you talking more or less INS as in the acronym for insurance? For the first one of these, inopportunely, I have no clue. To work for an insurance agency or company, you vitally need to find out the requirements for respectively business you apply to as many of them will own different requirements for different positions. You will need an insurance license to deal in and service insurance accounts which is tested for and provided by each state political affairs.
Good luck to you!
