Freelance work on a dependent visa

Hi all!

TL;DR: How do I change a dependent visa to allow freelance part-time (online) the work from my home country?

My wife is here on the usual English teaching Visa and I recently got a dependent visa to join her here.

I got the visa thankfully and have been here for a month with no issues whatsoever.

I know I'm not able to work with my current legal status, but I'm a little unsure about the process of getting a visa to engage in work outside of designated activities. I've seen I can have a company here couch for me to get part time work, but I haven't had any luck figuring out how to make it work if I can still work from the USA.

I know I'll never be able to exceed 28h of work per month, or be allowed to make more than my wife, but I was a therapist in NJ before I moved back here. There's no issue from my old clinic to me doing freelance work from abroad, but I don't want to risk my legal status by just working quietly and hoping no one notices.

Thanks for the help!
