I ain't sure $300,000 is enough for you to immigrate with. There are countries that accept investment for immigration (USA, for example, has EB-1 program with the requirement that you employ 10 or more workers for 2 years). Even so, if I were you, I would start looking for ways to get out of China when I have the money to do so.What would you do if you were me?
The following is the general situation of my life now. How should I get out of this predicament if you were me?
Sex: Male
Age: 42
Marriage: Divorced after being betrayed, currently alone, no children
Language: Chinese and a little English
House: None
Job: Trading U.S. stocks for a living
Certificate: None
Skills: relatively high cognition, able to see the essence of things (my own opinion)
Financial situation: I have a capital of 200,000 US dollars. From 2018 to now, I have made a profit of almost 200,000 US dollars. I have spent 100,000 US dollars on daily expenses, and now I have 300,000 US dollars.
Dilemma: 1. The stock market is not good now and I can’t make money, but I can’t find a job without skills (it’s hard for people over 35 years old in my country to find a job). Now I can only use the existing funds to maintain my life.
2 I am worried that in the future, my country will be prohibited from trading U.S. stocks, and it will even be prohibited to remit U.S. dollars to me or to other countries.
So you live in Seattle, eh? Now your cover is blown.Get out of China.
At least 1/3 of the Chinese in Seattle, WA can tell you how.

In which country do you apply for the fund? If it were my country, it would be difficult
What are the requirements for applying for funds from other countries?

Yes, I have also thought that if the situation is tense, I will transfer, but my passport can only stay in Vietnam for a maximum of 90 daysPoker? Are you talking about a card game? My English is not good, I use a translation toolGive poker a try.
Move to Vietnam, put most of your money in dividend portfolio (or those options ETF for >10% annual yield), then just grind at poker...
You're single with no kids, stop worrying like a biatch.
