Normally it takes really fast, less than a day. It all depends on the amount of information you filled up and the quality of your photos uploaded. The more information you provide about yourself, such as biography, better photos, etc, the faster your portfolio will be approved.

This is to help keeping the website with quality content. We want quality models to be stored here, so when visitors come browsing models here, they won't see any user with less information or blur or fake photos.

If your profile was created with little information filled, then you might result in profile rejection.
