I’m in Taiwan. How can I reach a mostly US audience on TikTok?

I’m an indie app dev based in Taiwan, and I want to start posting 3 TikToks a day about my app.

My main target audience is in the US, so I’m wondering if there’s a reliable way to reach mostly US viewers while posting from Taiwan.

Do I need a US-based account, SIM/eSIM, VPN, or are there other factors that matter more, like content, language, posting time, or hashtags?

Would love to hear from anyone who has experience with this.
