I'm not in modelling industry but i know doesn't matter where you live, when you sign contract you have just responsibility to be available according to your schedule and shooting, anywhere you are, you need you end up available.. Plus, Shootings don't take place in one area. Entirely depends on the type of modelling you're in.
For those who are in the modelling industry, do you need to live close to the agency office, or you can live anywhere and still work as a model with that agency?
Starting out is different from being established and famous.
If you're starting out ... You need to be close enough to travel to the agency. This is because most of the jobs the agency will give you are in their local area.
