It's really important that you don't go over your working cap, as this is illegal.
When you submit your documents when signing up with Stint, you will be required to input any hourly cap on your working Visa. Hours from multiple jobs will be cumulative, meaning everything contributes to your total cap. So if you have any other jobs, you need to let us know about these too.
This is required as we need to make sure that you do not exceed your working cap in order to comply with your Visa requirements.
