Scott and Vincent definitely play by the rules. I've seen other agencies that charge ~20% less, but I haven't contemplated changing horses because renewals with Scott are insanely easy, and he got me 5 years, in spite of my B work permit (this is not illegal).

The biggest barrier I can think of in your case getting a Chinese company to hire you. You don't necessarily need to do any actual work, but the company will be on the line for you, and front your taxes (which, can be very low).

Before I got my RP, I used M visas (F prior to that), but that ship sailed pre-COVID, and these days, companies are frequently subjected to visa inspections.

There are presumably some non-work related residence permits on offer (e.g. one of our members recently received a humanitarian visa). And, F might be possible if you get a really strong invitation letter (e.g. from a government entity). I encourage you to email Scott in order to get an overview of your options. His advice is free.
