Teachers Council is able to place you in any state where your credentials and level of education allow you to teach*. We place teachers all around the country depending on school position availability, and your unique area of expertise. Therefore we cannot say we only work in specific states. If you have any specific preferences during the placement process, you can always let us know and we will do our best to focus on those areas. However, we cannot guarantee that there will immediately be a school willing to host a J1 teacher within your preferred area, so it may add some time to the application. If you are willing to be placed anywhere in the U.S., then that expedites the placement process. That said, it is of course your choice where you ultimately decide to work, and you do not have to accept placement anywhere that you do not want to.
*If you wish to be able to work in a public school system, you must be able to acquire the appropriate license or certificate to teach in the public school district. Teacher license and certification requirements for public schools are governed by the State Department of Education in each U.S. state. Private school teachers typically have less requirements to fulfill in terms of certification, but again, this varies by U.S. state.
