Is it safe to use Webull as a non-US investor?

I am a non-US citizen and have never been to the US, either.

My portfolio size is almost 40K USD now, and I hope to add 60K every year.

I like Webull over Schwab/Ameritrade because of it's simple interface.

But I have concern over Chinese ownership. I don't live in US, so I don't think I can do much if they disappear with my money.

Are these concerns justified? Should I stick with Schwab?
