Passive income strategy with 30% rate

Hello guys, I wanna hear your thoughts about my goal to create the best passive income possible. I'm 31yo and I live in an asian country w/o tax agreement with USA so my US dividend would be taxed by 30% (i'm not US citizen). This is a big amount. My initial plan was to buy a 50/50 folio splited between SCHD (or other dividend ETF) and S&P to have both growth and value stocks. What would you do if you had 30% tax rate on ur dividend ? Stick to this strategy or do a FIRE exit (selling 3-4% of yr folio each year?) Thank you :)
