Legal & Tax Counsel for a Start-Up

I am starting a Business in the Eyewear industry and will be raising funds for production via Kickstarter. Being from Egypt, I can only do that if I register my Business in one of the countries approved by the platform. I found the easiest way would be registering in the USA via "Atlas by Stripe".

This is where I need the help of a legal specialist, I have a few questions regarding that service and how I can ensure I reap the benefits from this plan without any downsides.

Thank you!
