An LLC has "members" which are similar to "shareholders" in a C-Corporation. A member is someone who owns a share of the company. One important thing about an LLC is that it is a "pass-through" entity, which means that if an LLC makes $100 in profits in one year, and you are a member owning 50%, then 50% of those profits (i.e. $50) show up as personal income on your own tax returns even if you don't pay yourself those profits. If you distribute those profits to the members of the LLC later, then the distributions are tax-free (since you already paid the taxes prior). That is different from a C-Corp, in which the corporation pays corporate tax (after the 2017 tax cuts, it's 21%) on profits. Then, the corporation can pay its employees or distribute to its shareholders, and those distributions are generally taxed as income. So in this way, an LLC gives you some tax advantage over a C-Corp.

LittleHorse's structure is slightly complex, but the most important part of it (LittleHorse Enterprises LLC) was created using ZenBusiness. It is quite cheap, and they have registered agent services. I actually incorporated it in Nevada, since the LLC laws in Nevada are slightly simpler than Delaware

Delaware is the "de-facto" state for creating a C-Corp in, but I know that Elon Musk is not a fan of it 😂 due to some perceived excessive restrictions on what the owners of the corporation can do

So the TLDR: 1. Don't know about requirements for US Citizenship 2. For just a simple LLC, ZenBusiness can work 3. Taxes are very different for LLC and C-Corporation 4. Maybe might be worth looking into an S-Corporation if you can't get an LLC without being a US Citizen 5. Almost all (actually, maybe all) venture-backed startups are C-Corps because that's the only structure that really makes sense for outside investors 6. Check out Zen Business to create an LLC quickly and get a registered agent: https://zenbusiness.com

and most importantly: I'm not a lawyer so check all of this

I spent two days researching this and ended up deciding to make LittleHorse an LLC since we're not pursuing venture funding.
