modeling applications as a new model.

So recently I have applied to some well known modeling agencies based in LA and some in New York a few days ago. I am wondering how long it takes for these agencies to reach out if they think you are fit for their agency. I applied for IMG models, Next Management, Wilhelmina, Otto Models, Ford Models and The Society models. I know the chances of getting into any of these agencies is a slim to none chance but I still wanted to try because you never know yk? I just want to know around how long it takes for these agencies to reply back if they find you interesting. I’ve always wanted to model since I was a kid and another thing that motivated me to apply is that through out the years i’ve had a lot of strangers tell me I need to model. So I guess i’ve gained confidence to try and apply to some agencies. Obviously applying to the big ones for a first try looks dumb and it’s highly likely I won’t get in but it’s worth to try. Just curious about the average response time. Thank you!
