Changing jobs teaching to something different

Hello. I'm currently an English teacher but I'm looking to change jobs. The job I want to change to is completely different from what I'm doing now. There are some questions that I have.

1. I know that I will have to report this change of status to the immigration office. My question is, is this before or after quitting my current job?
2. Will I need a new Certificate of Eligibility?
3. Are there other things that I have to do before switching jobs?

Thank you for all the help you can offer!

If your job falls in another category, you need to change your status of residence (visa category). Failure to do so would be the same as working without a visa.

You can't change your visa based on what you want to do, only for the job you have. So the time to change would be after you have a contact from your new place of employment, then you can go in and request the change.

Thank you! So you guys mean I can start my new job without a new visa and report the change within 14 days?

The thing is, I think I will be working "illegally" if I did that because my current visa doesn't allow me to do the next job.

You must apply for a change of status and wait for it to be granted before you start working at your new job.

If you work before the change is granted, you work illegally, without quotes.

After you get your contract, but before you start the job, you apply for the visa change. You do not need a new CoE.

Thank you for the info!

That means I will need to be jobless until I get my new visa, is that correct?

Sort of. You can also continue your old job.

You should be "between jobs" since you quit one and are just waiting to begin at your new job. That is just semantics though.
