​Business idea for someone who is from Serbia but have USA LLC

Hi everyone, I’m from Serbia (non-US resident) and I have an active Wyoming LLC, plus Stripe and Mercury.

My original plan was tech consulting, but it didn’t work out. I’m keeping the LLC open and I’m trying to find any realistic way to earn income tied to the US market and get paid in USD through this setup.

I’m open to all ideas, for example:

Starting a US-facing agency (marketing/dev/VA/customer support, etc.) Outsourcing work to people from Serbia/Balkans while selling to US clients Productized services / retainers Digital products, simple SaaS, subscriptions Any “US-only” type of work or opportunities that can be done remotely (if that exists) Anything else that makes sense for a non-resident using a US LLC + Stripe/Mercury

What I’m really trying to understand:

What business models actually work for someone in my situation? Are there things you can legally do only because you have a US LLC + US payment/banking? What are the biggest compliance/tax pitfalls for non-residents I should avoid?

In Serbia the average salary is around ~$1,000/month, so even modest USD income would matter a lot.

Any advice or real examples are appreciated. Thanks!
