Yes! And I encourage you to do so! This does apply to those models that have only signed non-exclusive contracts however.

Most professional working models have representation in every major city. This is the difference between those models who only work once and a while and those who actually make a profession out of modeling in smaller markets.
Keep in mind however; if you are with a high fashion agency they most likely will have you under an exclusive contract. So either you will only work through their agency or they will find you representation in other cities on their own- serving as your mother agent.If you live in a smaller market- do not get enticed by signing an exclusive contract. Most likely they will not have enough work to keep you busy. If they insist- ask them if you can work on a non exclusive basis for a three month period. If you are working a ton- then sign- if not stay non exclusive!
